GENERAL DESCRIPTION

The ADV®7320/ADV7321 are high speed, digital-to-analog

encoders on single monolithic chips. They include six high

speed NSV video D/A converters with TTL compatible inputs.

They have separate 8-/10-, 16-/20-, and 24-/30-bit input ports

that accept data in high definition and/or standard definition

video format. For all standards, external horizontal, vertical,

and blanking signals or EAV/SAV timing codes control the

insertion of appropriate synchronization signals into the digital

data stream and, therefore, the output signal.

The ADV7320/ADV7321 is a Pb-free environmentally friendly

product. It is manufactured using the most up-to-date materials

and processes. The coating on the leads of each device is 100%

pure Sn electroplate. The device is suitable for Pb-free

applications and is able to withstand surface-mount soldering

up to 255°C ( 5°C).

In addition, it is backward-compatible with conventional SnPb

soldering processes. This means that the electroplated Sn

coating can be soldered with Sn/Pb solder pastes at

conventional reflow temperatures of 220°C to 235°C.

ESD CAUTION

ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily

accumulate on the human body and test equipment and can discharge without detection. Although

this product features proprietary ESD protection circuitry, permanent damage may occur on devices

subjected to high energy electrostatic discharges. Therefore, proper ESD precautions are

recommended to avoid performance degradation or loss of functionality.

MPU PORT DESCRIPTION

correct transmitted address. The R/ bit determines the

direction of the data.

W

The ADV7320/ADV7321 support a 2-wire serial (I²C-

compatible) microprocessor bus driving multiple peripherals.

This port operates in an open-drain configuration. Two inputs,

serial data (SDA) and serial clock (SCL), carry information

between any device connected to the bus and the ADV7320/

ADV7321. Each slave device is recognized by a unique address.

The ADV7320/ADV7321 have four possible slave addresses for

both read and write operations. These are unique addresses for

each device and are illustrated in Figure 44. The LSB sets either

a read or write operation. Logic 1 corresponds to a read

operation, while Logic 0 corresponds to a write operation. A1 is

enabled by setting the ALSB pin of the ADV7320/ADV7321 to

Logic 0 or Logic 1. When ALSB is set to 1, there is greater input

bandwidth on the I²C lines, which allows high speed data

transfers on this bus. When ALSB is set to 0, there is reduced

input bandwidth on the I²C lines, which means that pulses of

less than 50 ns will not pass into the I²C internal controller. This

mode is recommended for noisy systems.

Logic 0 on the LSB of the first byte means that the master will

write information to the peripheral. Logic 1 on the LSB of the

first byte means that the master will read information from the

peripheral.

The ADV7320/ADV7321 act as standard slave devices on the

bus. The data on the SDA pin is eight bits long, supporting the

7-bit addresses plus the R/ bit. It interprets the first byte as

W

the device address and the second byte as the starting

subaddress. There is a subaddress auto-increment facility. This

allows data to be written to or read from registers in ascending

subaddress sequence starting at any valid subaddress. A data

transfer is always terminated by a stop condition. The user can

also access any unique subaddress register on a one-by-one

basis without updating all the registers.

Stop and start conditions can be detected at any stage during

the data transfer. If these conditions are asserted out of

sequence with normal read and write operations, then they

cause an immediate jump to the idle condition. During a given

SCL high period, the user should only issue a start condition, a

stop condition, or a stop condition followed by a start

condition. If an invalid subaddress is issued by the user, the

ADV7320/ADV7321 will not issue an acknowledge and will

return to the idle condition. If the user utilizes the auto-

increment method of addressing the encoder and exceeds the

highest subaddress, the following actions are taken:

To control the various devices on the bus, the following

protocol must be followed. First, the master initiates a data

transfer by establishing a start condition, defined by a high-to-

low transition on SDA while SCL remains high. This indicates

that an address/data stream will follow. All peripherals respond

to the start condition and shift the next eight bits (7-bit address

Before writing to the subcarrier frequency registers, it is required

to reset ADV7320/ADV7321 at least once after power-up.

The four subcarrier frequency registers must be updated,

starting with Subcarrier Frequency Register 0 and ending with

Subcarrier Frequency Register 3. The subcarrier frequency will

only update after the last subcarrier frequency register byte has

been received by the ADV7320/ADV7321.

+ R/ bit). The bits are transferred from MSB down to LSB.

W

The peripheral that recognizes the transmitted address

responds by pulling the data line low during the ninth clock

pulse. This is known as an acknowledge bit. All other devices

withdraw from the bus at this point and maintain an idle

condition. The idle condition is where the device monitors the

SDA and SCL lines waiting for the start condition and the

Figure 46 illustrates an example of data transfer for a write

sequence and the start and stop conditions. Figure 47 shows bus

write and read sequences.

REGISTER ACCESS

The MPU can write to or read from all registers of the

REGISTER PROGRAMMING

ADV7320/ADV7321 except the subaddress registers, which are

write only registers. The subaddress register determines which

register the next read or write operation will access. All

communication with the part through the bus starts with an

access to the subaddress register. A read/write operation is then

performed from/to the target address, which increments to the

next address until a stop command is performed on the bus.

The following tables describe the functionality of each register.

All registers can be read from as well as written to, unless

otherwise stated.

SUBADDRESS REGISTER (SR7 TO SR0)

The communication register is an 8-bit write only register. After

the encoder’s bus is accessed and a read/write operation is

selected, the subaddress is set up. The subaddress register

determines to or from which register the operation takes place.

INPUT CONFIGURATION

When 10-bit input data is applied, the following bits must be set

to 1:

PROGRESSIVE SCAN ONLY OR HDTV ONLY

Address[0x01]: Input Mode = 001 or 010, Respectively

Address 0x13, Bit 2 (HD 10-bit enable)

Address 0x48, Bit 4 (SD 10-bit enable)

YCrCb progressive scan, HDTV, or any other HD YCrCb data

can be input in 4:2:2 or 4:4:4. In 4:2:2 input mode, the Y data is

input on Pins Y9 to Y0 and the CrCb data is input on Pins C9 to

C0. In 4:4:4 input mode, Y data is input on Pins Y9 to Y0, Cb data

is input on Pins C9 to C0, and Cr data is input on Pins S9 to S0.

If the YCrCb data does not conform to SMPTE 293M (525p),

ITU-R BT.1358M (625p), SMPTE 274M (1080i), SMPTE 296M

(720p), SMPTE 240M (1035i), or BTA-T1004/1362, the async

timing mode must be used. RGB data can only be input in

4:4:4 format in PS or HDTV input modes when HD RGB input

is enabled. G data is input on Pins Y9 to Y0, R data is input on

Pins S9 to S0, and B data is input on Pins C9 to C0. The clock

signal must be input on Pin CLKIN_A.

Note that the ADV7320 defaults to simultaneous standard

definition and progressive scan upon power-up (Address[0x01]:

Input Mode = 011).

STANDARD DEFINITION ONLY

Address[0x01]: Input Mode = 000

The 8-/10-bit, multiplexed input data is input on Pins S9 to S0

(or Pins Y9 to Y0, depending on Register Address 0x01, Bit 7),

with S0 being the LSB in 10-bit input mode (see Table 21). Input

standards supported are ITU-R BT.601/656. In 16-/20-bit input

mode, the Y pixel data is input on Pins S9 to S2 and CrCb data

is input on Pins Y9 to Y2 (see Table 21).

interleaved onto a single 10-bit bus, Pins Y9 to Y0 are used for

the input port. The input data is to be input at 27 MHz, with the

data being clocked upon the rising and falling edges of the input

clock. The input mode register at Address 0x01 is set

accordingly. If the YCrCb data does not conform to SMPTE

293M (525p), ITU-R BT.1358M (625p), SMPTE 274M (1080i),

SMPTE 296M (720p), SMPTE 240M (1035i), or BTA-T1004,

b. In subcarrier phase reset, a low-to-high transition on

the RTC_SCR_TR pin (Pin 31) resets the subcarrier

phase to zero on the field following the subcarrier

phase reset when the SD RTC/TR/SCR control bits at

Address 0x44 are set to 01.

HD TIMING RESET

A timing reset is achieved by toggling the HD timing reset control

bit [Subaddress 0x14, Bit 0] from 0 to 1. In this state, the horizontal

and vertical counters remain reset. When this bit is set back to 0,

the internal counters resume counting.

This reset signal must be held high for a minimum of

one clock cycle.

The minimum time the pin must be held high is one clock

cycle; otherwise, this reset signal might not be recognized. This

timing reset applies to the HD timing counters only.

Because the field counter is not reset, it is

recommended that the reset signal is applied in Field 7

(PAL) or Field 3 (NTSC). The reset of the phase will

then occur on the next field, i.e., Field 1, lined up

correctly with the internal counters. The field count

register at Address 0x7B can be used to identify the

number of the active field.

SD REAL-TIME CONTROL, SUBCARRIER RESET,

AND TIMING RESET

[Subaddress 0x44, Bits 2 and 1]

Together with the RTC_SCR_TR pin and SD Mode Register 3

[Address 0x44, Bits 1 and 2], the ADV7320/ADV7321 can be

used in (a) timing reset mode, (b) subcarrier phase reset mode,

or (c) RTC mode.

c. In RTC mode, the ADV7320/ADV7321 can be used to

lock to an external video source. The real-time control

mode allows the ADV7320/ADV7321 to automatically

alter the subcarrier frequency to compensate for line

length variations. When the part is connected to a

device, such as an ADV7183A video decoder (see

Figure 62), that outputs a digital data stream in the

RTC format, the part will automatically change to the

compensated subcarrier frequency on a line-by-line

basis. This digital data stream is 67 bits wide and the

subcarrier is contained in Bits 0 to 21. Each bit is two

clock cycles long. Write 0x00 into all four subcarrier

frequency registers when this mode is used.

a. A timing reset is achieved in a low-to-high transition

on the RTC_SCR_TR pin (Pin 31). In this state, the

horizontal and vertical counters remain reset. Upon

releasing this pin (set to low), the internal counters

resume counting, starting with Field 1, and the

subcarrier phase is reset.

The minimum time the pin must be held high is one

clock cycle; otherwise, this reset signal might not be

recognized. This timing reset applies to the SD timing

counters only.

SUBCARRIER FREQUENCY REGISTERS

The ADV7320/ADV7321 accepts input data that contains VBI

data (such as CGMS, WSS, VITS) in SD and HD modes.

[Subaddresses 0x4C to 0x4F]

Four 8-bit registers are used to set up the subcarrier frequency.

The value of these registers is calculated using the equation

For the SMPTE 293M (525p) standard, VBI data can be

inserted on Lines 13 to 42 of each frame, or on Lines 6 to 43 for

the ITU-R BT.1358 (625p) standard.

This data can be present on Lines 10 to 20 for SD NTSC and on

Lines 7 to 22 for PAL.

where the sum is rounded to the nearest integer.

For example, in NTSC mode

If VBI is disabled [Address 0x11, Bit 4 for HD; Address 0x43,

Bit 4 for SD], VBI data is not present at the output and the

entire VBI is blanked. These control bits are valid in all master

and slave modes.

automatically blanks the VBI to standard.

See the MPU Port Description section for more details on

accessing the subcarrier frequency registers.

If CGMS is enabled and VBI is disabled, the CGMS data will

nevertheless be available at the output.

Programming the F_SC

See Appendix 1—Copy Generation Management System.

The subcarrier register value is divided into 4 F_SCregisters as

shown above. To load the value into the encoder, users must

write to the F_SCregisters in sequence, starting with F_SC0. The

value is not loaded until the F_SC4 write is complete.

Note that the ADV7320/ADV7321 power-up value for F_SC0 is

0x1E. For precise NTSC F_SC, write 0x1F to this register.

¹Pass-band ripple is the maximum fluctuation from the 0 dB response in the

pass band, measured in dB. The pass band is defined to have 0 Hz to fc (Hz)

frequency limits for a low-pass filter, and 0 Hz to f1 (Hz) and f2 (Hz) to infinity

for a notch filter, where fc, f1, and f2 are the −3 dB points.

In addition to the chroma filters listed in Table 27, the

ADV7320/ADV7321 contains an SSAF filter specifically

designed for the color difference component outputs, U and V.

This filter has a cutoff frequency of about 2.7 MHz and a gain of

white, black, and saturated primary and complementary colors

conform to the ITU-R BT.601-4 standard.

Table 29 shows sample color values that can be programmed

into the color registers when the output standard selection is

set to EIA 770.2.

Rev. 0 | Page 49 of 88

ADV7320/ADV7321

R = Y + 1.575Pr

If YPrPb output is selected, the following equations are used:

G = Y − 0.468Pr − 0.187Pb

B = Y + 1.855Pb

Y = GY × Y

U = BU × Pb

V = RV × Pr

This is reflected in the preprogrammed values for GY = 0x13B,

GU = 0x3B, GV = 0x93, BU = 0x248, and RV = 0x1F0.

Upon power-up, the RGB matrix is programmed with the

default values in Table 31.

If RGB matrix is enabled and another input standard (such as

SD or PS) is used, the scale values for GY, GU, GV, BU, and RV

must be adjusted according to this input standard color space.

The user should consider that the color component conversion

might use different scale values. For example, SMPTE 293M

uses the following conversion:

When the manual RGB matrix adjust feature is not enabled, the

ADV7320/ADV7321 automatically scales YCrCb inputs to all

standards supported by this part as selected by the input mode

Register 0x01 [6:4].

The manual RGB matrix adjust feature can be used to control

the HD output levels in cases where the video output does not

conform to the standard due to altering the DAC output stages

such as termination resistors. The programmable RGB matrix is

used for external HD/PS data and is not functional when internal

test patterns are enabled. To adjust Registers 0x05 to 0x09, the

manual RGB matrix adjust must be enabled [Register 0x02,

Bit 3 =1].

SD Luma and Color Control

[Subaddresses 0x5C, 0x5D, 0x5E, 0x5F]

SD Y Scale, SD Cr Scale, and SD Cb Scale are three 10-bit-wide

control registers that scale the Y, Cb, and Cr output levels.

Programming the RGB Matrix

Each of these registers represents the value required to scale the

Cb or Cr level from 0.0 to 2.0 and the Y level from 0.0 to 1.5 of

its initial level. The value of these 10 bits is calculated using the

following equation:

If custom manipulation of coefficients is required, enable the

RGB matrix in Address 0x02, Bit 3, set the output to RGB

[Address 0x02, Bit 5], and disable sync on PrPb (default)

[Address 0x15, Bit 2]. Enabling sync on RGB is optional

[Address 0x02, Bit 4].

Y, Cr, or Cb Scalar Value = Scale Factor × 512

For example,

GY at Addresses 0x03 and 0x05 controls the green signal output

levels. BU at Addresses 0x04 and 0x08 control the blue signal

output levels, and RV at Addresses 0x04 and 0x09 control the red

signal output levels. To control YPrPb output levels, enable the

YUV output [Address 0x02, Bit 5]. In this case GY [Address 0x05;

Address 0x03, Bits 0 and 1] is used for the Y output, RV

[Address 0x09; Address 0x04, Bits 0 and 1] is used for the Pr

output, and BU [Address 0x08; Address 0x04, Bits 2 and 3] is

used for the Pb output.

Scale Factor = 1.18

Y, Cb, or Cr Scale Value = 1.18 × 512 = 665.6

Y, Cb, or Cr Scale Value = 665 (rounded to the nearest

integer)

Y, Cb, or Cr Scale Value = 1010 0110 01b

Address 0x5C, SD LSB Register = 0x15

Address 0x5D, SD Y Scale Register = 0xA6

Address 0x5E, SD Cb Scale Register = 0xA6

Address 0x5F, SD Cr Scale Register = 0xA6

If RGB output is selected, the RGB matrix scaler uses the

following equations:

G = GY × Y + GU × Pb + GV × Pr

B = GY × Y + BU × Pb

Note that this feature affects all interlaced output signals, i.e.,

CVBS, Y-C, YPrPb, and RGB.

R = GY × Y + RV × Pr

SD Hue Adjust Value

For example,

[Subaddress 0x60]

1. To add +20 IRE brightness level to an NTSC signal with

pedestal, write 0x28 to Address 0x61, SD brightness.

The hue adjust value is used to adjust the hue on the composite

and chroma outputs.

0x[SD Brightness Value] =

These eight bits represent the value required to vary the hue of

the video data, i.e., the variance in phase of the subcarrier

during active video with respect to the phase of the subcarrier

during the color burst. The ADV7320/ADV7321 provides a

range of 22.5° increments of 0.17578125°. For normal

operation (zero adjustment), this register is set to 0x80. Values

0xFF and 0x00 represent the upper and lower limits

(respectively) of adjustment attainable.

0x[IRE Value × 2.015631] =

0x[20 × 2.015631] = 0x[40.31262] = 0x28

2. To add –7 IRE brightness level to a PAL signal, write 0x72 to

Address 0x61, SD brightness.

[IRE Value| × 2.075631

[7 × 2.015631] = [14.109417] = 0001110b

Hue Adjust (°) = 0.17578125° (HCR_d− 128) for positive hue

adjust value.

[0001110] into twos complement = [1110010]b = 0x72

SD Brightness Control

[Subaddress 0x61]

The brightness is controlled by adding a programmable setup

level onto the scaled Y data. This brightness level may be added

onto the scaled Y data. For NTSC with pedestal, the setup can

vary from 0 IRE to 22.5 IRE. For NTSC without pedestal and

for PAL, the setup can vary from −7.5 IRE to +15 IRE.

The brightness control register is an 8-bit register. Seven bits of

this 8-bit register are used to control the brightness level, which

can be a positive or negative value.

Double buffering can be activated on the following HD

registers: HD gamma A and gamma B curves and HD CGMS

registers.

SD Brightness Detect

[Subaddress 0x7A]

The ADV7320/ADV7321 allow monitoring the brightness level

of the incoming video data. Brightness detect is a read-only

register.

Double buffering can be activated on the following SD registers:

SD gamma A and gamma B curves, SD Y scale, SD U scale, SD V

scale, SD brightness, SD closed captioning, and SD Macrovision

Bits 5 to 0.

Double Buffering

[Subaddress 0x13, Bit 7; Subaddress 0x48, Bit 2]

Double buffered registers are updated once per field upon the

falling edge of the Vsync signal. Double buffering improves the

overall performance because modifications to register settings

will not be made during active video, but take effect upon the

start of the active video.

[Subaddresses 0x24 to 0x37 for HD,

Gamma correction is available for SD and HD video. For each

standard, there are twenty 8-bit-wide registers. They are used to

program the Gamma Correction Curves A and B. HD Gamma

Curve A is programmed at Addresses 0x24 to 0x2D, and HD

Gamma Curve B is programmed at 0x2E to 0x7. SD Gamma

Curve A is programmed at Addresses 0x66 to 0x6F, and SD

Gamma Curve B is programmed at Addresses 0x70 to 0x79.

300mV

Figure 70. Programmable DAC Gain—Positive and Negative Gain

In case A, the video output signal is gained. The absolute level

of the sync tip and blanking level both increase with respect to

the reference video output signal. The overall gain of the signal

is increased from the reference signal.

Generally gamma correction is applied to compensate for the

nonlinear relationship between signal input and brightness level

output (as perceived on the CRT). It can also be applied

wherever nonlinear processing is used.

In case B, the video output signal is reduced. The absolute level

of the sync tip and blanking level both decrease with respect to

the reference video output signal. The overall gain of the signal

is reduced from the reference signal.

Gamma correction uses the function

γ

Signal_OUT

=

(

Signal_IN

)

where γ = gamma power factor.

The range of this feature is specified for 7.5% of the nominal

output from the DACs. For example, if the output current of the

DAC is 4.33 mA, the DAC tune feature can change this output

current from 4.008 mA (−7.5%) to 4.658 mA (+7.5%).

Gamma correction is performed on the luma data only. The

user may choose either of two curves, Curve A or Curve B. At

any one time, only one of these curves can be used.

The reset value of the vid_out_ctrl registers is 0x00; therefore,

nominal DAC current is output. The following table is an

example of how the output current of the DACs varies for a

nominal 4.33 mA output current.

The response of the curve is programmed at 10 predefined

locations. In changing the values at these locations, the gamma

curve can be modified. Between these points, linear interpolation

is used to generate intermediate values. Considering the curve

to have a total length of 256 points, the 10 locations are at 24,

32, 48, 64, 80, 96, 128, 160, 192, and 224. Locations 0, 16, 240,

and 255 are fixed and cannot be changed.

The derivative of the incoming signal is compared to the three

235, although any value in the range of 0 to 255 can be used.

HD SHARPNESS FILTER AND ADAPTIVE FILTER

CONTROLS

[Subaddresses 0x20, 0x38 to 0x3D]

There are three filter modes available on the ADV7320/

ADV7321: sharpness filter mode and two adaptive filter modes.

The edges can then be attenuated with the settings in HD

adaptive filter gain 1, 2, and 3 registers, and HD sharpness filter

gain register.

HD Sharpness Filter Mode

To enhance or attenuate the Y signal in the frequency ranges

shown in Figure 73, the HD sharpness filter must be enabled

and the HD adaptive filter enable must be disabled.

According to the settings of the HD adaptive filter mode

control, there are two adaptive filter modes available:

1. Mode A is used when adaptive filter mode is set to 0.

In this case, Filter B (LPF) will be used in the adaptive

filter block. Also, only the programmed values for

Gain B in the HD sharpness filter gain and HD

Adaptive Filter Gain 1, 2, and 3 are applied when

needed. The Gain A values are fixed and cannot be

changed.

To select one of the 256 individual responses, the corresponding

gain values, which range from –8 to +7, for each filter must be

programmed into the HD sharpness filter gain register at

Address 0x20.

HD Adaptive Filter Mode

The HD adaptive filter threshold A, B, and C registers, the HD

adaptive filter gain 1, 2, and 3 registers, and the HD sharpness

gain register are used in adaptive filter mode. To activate the

adaptive filter control, the HD sharpness filter and the HD

adaptive filter must be enabled.

2. Mode B is used when adaptive filter mode is set to 1.

In this mode, a cascade of Filter A and Filter B is used.

Both settings for Gain A and Gain B in the HD

sharpness filter gain and HD Adaptive Filter Gain 1, 2,

and 3 become active when needed.

SD DIGITAL NOISE REDUCTION

[Subaddresses 0x63, 0x64, 0x65]

DNR is applied to the Y data only. A filter block selects the high

frequency, low amplitude components of the incoming signal

(DNR input select). The absolute value of the filter output is

compared to a programmable threshold value (DNR threshold

control). There are two DNR modes available: DNR mode and

DNR sharpness mode.

In DNR mode, if the absolute value of the filter output is

smaller than the threshold, it is assumed to be noise. A

programmable amount (coring gain border, coring gain data) of

this noise signal will be subtracted from the original signal. In

DNR sharpness mode, if the absolute value of the filter output is

less than the programmed threshold, it is assumed to be noise,

as before. Otherwise, if the level exceeds the threshold, now

being identified as a valid signal, a fraction of the signal (coring

gain border, coring gain data) will be added to the original

signal to boost high frequency components and sharpen the

video image.

In MPEG systems, it is common to process the video

information in blocks of 8 pixels × 8 pixels for MPEG2 systems,

or 16 pixels × 16 pixels for MPEG1 systems (block size control).

DNR can be applied to the resulting block transition areas that

are known to contain noise. Generally, the block transition area

contains two pixels. It is possible to define this area to contain

four pixels (border area).

It is also possible to compensate for variable block positioning

or differences in YCrCb pixel timing with the use of the DNR

block offset.

The digital noise reduction registers are three 8-bit registers.

They are used to control the DNR processing.

[Address 0x65, Bits 2 to 0]

Three bits are assigned to select the filter, which is applied to the

incoming Y data. The signal that lies in the pass band of the

selected filter is the signal that will be DNR processed. Figure 81

shows the filter responses selectable with this control.

DNR MODE CONTROL

When the active video edge feature is enabled, the first three

pixels and the last three pixels of the active video on the luma

channel are scaled so that maximum transitions on these pixels

are not possible. The scaling factors are ×1/8, ×1/2, and ×7/8.

All other active video passes through unprocessed.

[Address 0x65, Bit 4]

This bit controls the DNR mode selected. Logic 0 selects DNR

mode; Logic 1 selects DNR sharpness mode.

DNR works on the principle of defining low amplitude, high

frequency signals as probable noise and subtracting this noise

from the original signal.

SAV/EAV STEP EDGE CONTROL

The ADV7320/ADV7321 have the capability of controlling fast

rising and falling signals at the start and end of active video to

minimize ringing.

In DNR mode, it is possible to subtract a fraction of the signal

that lies below the set threshold, assumed to be noise, from the

original signal. The threshold is set in DNR Register 1.

An algorithm monitors SAV and EAV and determines when the

edges are rising or falling too fast. The result is reduced ringing

at the start and end of active video for fast transitions.

Subaddress 0x42, Bit 7 = 1, enables this feature.

When DNR sharpness mode is enabled, it is possible to add a

fraction of the signal that lies above the set threshold to the

DAC output traces on a PCB should be treated as transmission

lines. It is recommended that the DACs be placed as close as

possible to the output connector, with the analog output traces

being as short as possible (less than 3 inches). The DAC termi-

nation resistors should be placed as close as possible to the DAC

outputs and should overlay the PCB’s ground plane. As well as

minimizing reflections, short analog output traces will reduce

noise pickup due to neighboring digital circuitry.

Optimum performance is achieved by the use of 10 nF and

0.1 µF ceramic capacitors. Each group of V_AA, V_DD, or V_{DD_IO}

pins should be individually decoupled to ground. This should

be done by placing the capacitors as close as possible to the

device with the capacitor leads as short as possible, thus

minimizing lead inductance.

PCB BOARD LAYOUT

A 1 µF tantalum capacitor is recommended across the V_AA

supply in addition to 10 nF ceramic. See the circuit layout in

Figure 91.

The ADV7320/ADV7321 are optimally designed for lowest

noise performance of both radiated and conducted noise. To

complement the excellent noise performance of the ADV7320/

ADV7321, it is imperative that great care be given to the PC

board layout.

Digital Signal Interconnect

The digital signal lines should be isolated as much as possible

from the analog outputs and other analog circuitry. Digital

signal lines should not overlay the analog power plane.

The layout should be optimized for lowest noise on the

ADV7320/ ADV7321 power and ground lines. This can be

achieved by shielding the digital inputs and providing good

decoupling. The lead length between groups of V_AAand AGND,

V_DDand DGND, and V_{DD_IO}and GND_IO pins should be kept

as short as possible to minimized inductive ringing.

Due to the high clock rates used, avoid long clock lines to the

ADV7320/ADV7321 to minimize noise pickup.

Any active pull-up termination resistors for the digital inputs

should be connected to the digital power plane and not the

analog power plane.

It is recommended that a 4-layer printed circuit board is used,

with power and ground planes separating the layer of the signal

carrying traces of the components and solder side layer. Com-

ponent placement should be carefully considered in order to

separate noisy circuits, such as crystal clocks, high speed logic

circuitry, and analog circuitry.

Analog Signal Interconnect

Locate the ADV7320/ADV7321 as close as possible to the

output connectors to minimize noise pickup and reflections due

to impedance mismatch.

Rev. 0 | Page 63 of 88

ADV7320/ADV7321

For optimum performance, the analog outputs should each be

source- and load-terminated, as shown in Figure 91. The

termination resistors should be as close as possible to the

ADV7320/ADV7321 to minimize reflections.

For optimum performance, it is recommended that all

decoupling and external components relating to the

ADV7320/ADV7321 are located on the same side of the PCB

and as close as possible to the ADV7320/ADV7321. Any

unused inputs should be tied to ground.

1080i System

When PS CGMS is enabled [Subaddress 0x12, Bit 6 = 1], CGMS

data is inserted on Line 41. The 525p CGMS data registers are at

Addresses 0x21, 0x22, and 0x23.

CGMS data is applied to Line 19 and Line 582 of the luminance

vertical blanking interval.

CGMS FUNCTIONALITY

625p

If SD CGMS CRC [Address 0x59, Bit 4] or PS/HD CGMS CRC

[Subaddress 0x12, Bit 7] is set to Logic 1, the last six bits, C19 to

C14, which comprise the 6-bit CRC check sequence, are

automatically calculated on the ADV7320/ADV7321. This

calculation is based on the lower 14 bits (C0 to C13) of the data

in the data registers and output with the remaining 14 bits to

form the complete 20 bits of the CGMS data. The calculation of

the CRC sequence is based on the polynomial ×6 + x + 1 with a

preset value of 111111. If SD CGMS CRC [Address 0x59, Bit 4]

and PS/HD CGMS CRC [Address 0x12, Bit 7] are set to Logic 0,

all 20 bits (C0 to C19) are output directly from the CGMS

registers (CRC must be calculated by the user manually).

The 625p CGMS conforms to the IEC62375 (2004) 625p/50

video system’s analog interface for the video and accompanying

data using the vertical blanking interval.

When PS CGMS is enabled [Subaddress 0x12, Bit 6 = 1], CGMS

data is inserted on Line 43. The 625p CGMS data registers are at

Addresses 0x22, and 0x23.

APPENDIX 3—SD CLOSED CAPTIONING

[Subaddresses 0x51 to 0x54]

FCC Code of Federal Regulations (CFR) 47 section 15.119 and

EIA608 describe the closed captioning information for Line 21

and Line 284.

The ADV7320/ADV7321 support closed captioning conforming

to the standard television synchronizing waveform for color

transmission. Closed captioning is transmitted during the

blanked active line time of Line 21 of the odd fields and Line

284 of the even fields.

The ADV7320/ADV7321 use a single buffering method. This

means that the closed captioning buffer is only 1 byte deep;

therefore, there will be no frame delay in outputting the closed

captioning data, unlike other 2-byte-deep buffering systems.

The data must be loaded one line before it is output on Line 21

and Line 284. A typical implementation of this method is to use

Closed captioning consists of a 7-cycle sinusoidal burst that is

frequency and phase locked to the caption data. After the clock

run-in signal, the blanking level is held for two data bits and is

followed by Logic 1 start bit. Sixteen bits of data follow the start

bit. These consist of two 8-bit bytes, seven data bits, and one

odd parity bit. The data for these bytes is stored in the SD

closed captioning registers [Addresses 0x53 to 0x54].

to interrupt a microprocessor, which in turn will load

VSYNC

the new data (2 bytes) in every field. If no new data is required

for transmission, 0s must be inserted in both data registers; this

is called nulling. It is also important to load control codes, all of

which are double bytes, on Line 21, or a TV will not recognize

them. If there is a message such as “Hello World” that has an

odd number of characters, it is important to add a blank

character at the end so that the end-of-caption, 2-byte control

code lands in the same field.

The ADV7320/ADV7321 also support the extended closed

captioning operation, which is active during even fields and

encoded on Scan Line 284. The data for this operation is stored

in the SD closed captioning registers [Addresses 0x51 to 0x52].

All clock run-in signals and timing to support closed captioning

on Lines 21 and 284 are generated automatically by the

ADV7320/ ADV7321. All pixels inputs are ignored during

Lines 21 and 284 if closed captioning is enabled.

The register settings in Table 41 are used to generate an SD

NTSC CVBS output on DAC A, S-video on DACs B and C, and

YPrPb on DACs D, E, and F. Upon power-up, the subcarrier

registers are programmed with the appropriate values for

NTSC. All other registers are set as normal/default.

The register settings in Table 43 are used to generate a 525p

hatch pattern on DAC D, E, and F. All other registers are set as

normal/default.
