ADV7850  
GENERAL DESCRIPTION  
also includes an integrated equalizer that ensures robust opera-  
tion of the interface with cable lengths up to 30 meters. The HDMI  
receiver has advanced audio functionality, such as a mute flag,  
that prevents audible extraneous noise in the audio output.  
The ADV7850 is a high quality, single chip, multiformat video  
decoder graphics digitizer with an integrated 4:1 multiplexed  
HDMI® receiver.  
This multiformat 3D comb filter decoder supports the conversion  
of PAL, NTSC, and SECAM standards in the form of a composite  
or an S-Video input signal into a HDMI output stream. SCART  
and overlay functionality are enabled by the ability of the  
ADV7850 to process CVBS and standard definition RGB signals  
simultaneously.  
In addition, the HDMI receiver incorporates internal EDID  
support, which can be made available in full power, power-  
down, and power-off modes. An internal regulator supplies  
external EDID memory from the HDMI 5 V signal in power-  
off mode.  
The ADV7850 incorporates Xpressview™ fast switching on all  
HDMI input ports. Using the Analog Devices, Inc., hardware-  
based HDCP engine that minimizes software overhead,  
Xpressview technology allows fast switching between any two  
HDMI input ports in less than 1 second.  
The ADV7850 contains one main component processor (CP)  
that processes YPrPb and RGB component formats, including  
RGB graphics. The ADV7850 can operate in quad HDMI and  
analog input mode, thus allowing for fast switching between the  
analog video inputs and HDMI.  
The ADV7850 offers a flexible audio output port for the audio  
data decoded from the HDMI stream. HDMI audio formats,  
including super audio CD (SACD) via DSD, DST, and HBR are  
supported.  
The ADV7850 supports the decoding of a component RGB/  
YPrPb video signal into a HDMI output stream. The support  
for component video includes 525i, 625i, 525p, 625p, 720p,  
1080i, 1080p, and 1250i standards, as well as many other  
SMPTE and HD standards.  
The ADV7850 also features the single mode audio return  
channel (ARC) feature. ARC simplifies cabling by combining  
upstream audio capability in a conventional HDMI cable.  
The ADV7850 supports graphics digitization. The ADV7850 is  
capable of digitizing RGB graphics signals from VGA to UXGA  
rates and converting them into an HDMI output stream. Internal  
EDID RAM is available for one graphics port.  
The stereo audio ADC converts analog audio inputs and  
provides the data to the back end via the HDMI interface. The  
stereo audio DAC receives I2  
S data from the back end and  
The ADV7850 incorporates a quad input HDMI-compatible  
receiver that supports all HDTV formats up to 3D 1080p 60 Hz  
and 2160P 24 Hz.  
converts it to analog audio output. The audio output is available  
as both high impedance and a driven output, which is suitable  
for driving headphones directly.  
The ADV7850 supports full HDCP decryption with internal  
key storage. The ADV7850 features HDCP authentication on all  
ports simultaneously. The feature allows fast switching between  
HDMI ports. Sync measurements and status monitoring are  
also available for all HDMI ports. Each HDMI port has dedi-  
cated 5 V detect and hot plug assert pins. The HDMI receiver  
Fabricated in an advanced CMOS process, the ADV7850 is  
provided in a 19 mm × 19 mm, 425-ball, CSP_BGA, surface-  
mount, RoHS-compliant package, and is specified over the  
−20°C to +70°C temperature range.

The most efficient measurement solution is obtained using the  
package surface temperature to estimate the die temperature  
because this eliminates the variance associated with the θJA value.  
The maximum junction temperature (TJ MAX) of 125°C must not be  
exceeded. The following equation calculates the junction tempera-  
ture using the measured package surface temperature and applies  
only when no heat sink is used on the device under test (DUT):

POWER SUPPLY SEQUENCING  
In this case, care must be taken to ensure that a lower rated supply  
does not go above a higher rated supply level as the supplies are  
being established.  
POWER-UP SEQUENCE  
The recommended power-up sequence of the ADV7850 is as  
follows:  
POWER-DOWN SEQUENCE  
1. 3.3 V supplies  
2. 1.8 V supplies  
The ADV7850 supplies can be powered down simultaneously as  
long as the 3.3 V supply domain does not go below the 1.8 V  
supply domain.

ADV7850  
FUNCTIONAL OVERVIEW  
Internal E-EDID RAM  
Hot plug assert output pin for each HDMI port  
HDMI RECEIVER  
The ADV7850 front end incorporates a 4:1 multiplexed HDMI  
receiver with Xpressview fast switching technology and support  
for HDMI features including ARC and 3D TV. Building on the  
feature set of Analog Devices existing HDMI devices, the  
ADV7850 also offers support for all HDTV formats up to 3D  
1080p at 60 Hz and 2160p at 24 Hz. Xpressview fast switching  
technology, using the Analog Devices hardware-based HDCP  
engine that minimizes software overhead, allows switching  
between any two input ports in less than 1 second.  
ANALOG FRONT END  
The ADV7850 analog front end comprises four 170 MHz, 12-bit  
ADCs that digitize the analog video signal before applying it  
to the standard definition processor (SDP) or component  
processor (CP).  
The front end also includes a 13-channel input mux that enables  
multiple video signals to be applied to the ADV7850 without  
the requirement of an external mux.  
With the inclusion of HDCP 1.4, the ADV7850 can receive  
encrypted video content. The HDMI interface of the ADV7850  
allows for authentication of a video receiver, decryption of encoded  
data at the receiver, and renewal of that authentication during  
transmission, as specified by the HDCP 1.4 protocol. Repeater  
support is also offered by the ADV7850.  
Current and voltage clamp control loops ensure that any dc  
offsets are set properly for the video signal. The clamps are  
positioned in front of each ADC to ensure that the video signal  
remains within the range of the converter.  
The ADCs are configured to run up to 4× oversampling mode  
when decoding composite, S-Video, or SCART inputs. For  
component 525i, 625i, 525p, and 625p sources, 4× oversampling is  
performed. Higher frequency video standards can be 2× or 1×  
oversampled. Oversampling the video signals reduces the cost  
and complexity of external antialiasing filters with the benefit of  
an increased signal-to-noise ratio (SNR).  
The ADV7850 supports the audio return channel feature. There  
is a dedicated S/PDIF input on which audio can be received for  
retransmission on the HDMI input. Wide ranges of 3D video  
formats are supported, including frame packing up to 3D 1080p  
at 60 Hz and 2160p at 24 Hz.  
The HDMI receiver incorporates active equalization of the  
HDMI data signals. This equalization compensates for the high  
frequency losses inherent in HDMI and DVI cabling, especially  
at longer lengths and higher frequencies. It is capable of equaliz-  
ing for cable lengths up to 30 meters to achieve robust receiver  
performance at even the highest HDMI data rates.  
Optional internal antialiasing filters with programmable  
bandwidth are positioned in front of each ADC. These filters  
can be used to band-limit video signals, removing spurious out-  
of-band noise.  
The ADV7850 can support the simultaneous processing of  
CVBS and RGB standard definition signals to enable SCART  
compatibility and overlay functionality. A combination of  
CVBS and RGB inputs can be mixed with the output under the  
control of I2C registers.  
The HDMI receiver offers advanced audio functionality. It sup-  
ports multichannel I2S audio for up to eight channels. It also  
supports a six-DSD channel interface with each channel carry-  
ing an oversampled 1-bit representation of the audio signal as  
delivered on SACD. The ADV7850 can also receive HBR audio  
packet streams and outputs them through the HBR interface in  
an S/PDIF format conforming to the IEC 60958 standard.  
Analog front-end features include:  
Four 170 MHz, 12-bit NSV ADCs that enable 10-bit (SD)/  
12-bit (CP) video decoding  
The receiver contains an audio mute controller that can detect a  
variety of conditions that may result in audible extraneous noise  
in the audio output. On detection of these conditions, the audio  
signal can be muted to prevent audio clicks or pops.  
13-channel analog input mux that enables multiple source  
connections without the requirement of an external mux  
Four current and voltage clamp control loops that ensure  
any dc offsets are set properly for the video signal  
SCART functionality and SD RGB overlay on CVBS  
controlled by fastblank input  
SCART source switching detection through the TRI1 to TRI8  
inputs

ADV7850  
Data Sheet  
Advanced TBC with frame synchronization, which ensures  
nominal clock and data for nonstandard input  
Color controls that include hue, brightness, saturation,  
and contrast  
STANDARD DEFINITION PROCESSOR  
The SDP is capable of decoding a large selection of baseband  
video signals in composite, S-Video, and 525i/625i component  
formats. The video standards supported by the SDP include  
PAL, PAL 60, PAL M, PAL N, PAL NC, NTSC M/J, NTSC 4.43,  
and SECAM. The ADV7850 can automatically detect the video  
standard and process it accordingly.  
COMPONENT PROCESSOR  
The CP section of the ADV7850 is capable of decoding and  
digitizing a wide range of component video formats in any color  
space. Component video standards supported by the CP include  
525i, 625i, 525p, 625p, 720p, 1080i, 1080p, 1250i, VGA up to  
UXGA at 60 Hz, and many other standards.  
The SDP has a 3D temporal comb filter and a five-line adaptive  
2D comb filter that gives superior chrominance and luminance  
separation when decoding a composite video signal. This highly  
adaptive filter automatically adjusts its processing mode according  
to the video standard and signal quality with no user intervention  
required. The SDP has an IF filter block that compensates for  
attenuation in the high frequency chroma spectrum due to a tuner  
SAW filter. The SDP has specific luminance and chrominance  
parameter controls for brightness, contrast, saturation, and hue.  
The any-to-any, 3 × 3 CSC matrix is placed between the analog  
front end and the CP section. This enables YPbPr-to-RGB and  
RGB-to-YCbCr conversions. Many other standards of color  
space can be implemented using the color space converter.  
The CP section contains circuitry to enable the detection of  
Macrovision encoded YPbPr signals for 525i, 625i, 525p, and  
625p. It is designed to be fully robust when decoding these  
types of signals.  
The ADV7850 implements a patented Adaptive Digital Line  
Length Tracking (ADLLT™) algorithm to track varying video  
line lengths from sources such as a VCR. ADLLT enables the  
ADV7850 to track and decode poor quality video sources (such  
as VCRs) and noisy sources (such as tuner outputs, VCR players,  
and camcorders). Frame TBC ensures stable clock synchroniza-  
tion between the decoder and the downstream devices.  
CP features include:  
525i, 625i, 525p, 625p, 720p, 1080i, 1080p, and many other  
HDTV formats are supported  
Supports 720p at 24 Hz/25 Hz formats  
Manual adjustments including gain (contrast), offset  
(brightness), hue, and saturation  
The SDP also contains both a luma transient improvement (LTI)  
block and a chroma transient improvement (CTI) block. These  
increase the edge rate on the luma and chroma transitions,  
resulting in a sharper video image.  
Support for analog component YPbPr and RGB video  
formats with embedded synchronization, composite  
synchronization, or separate HS and VS  
Any-to-any, 3 × 3 CSC matrix that supports YCbCr-to-  
RGB and RGB-to-YCbCr, fully programmable or  
preprogrammable configurations  
Synchronization source polarity detector (SSPD) that  
determines the source and polarity of the synchronization  
signals that accompany the input video  
Macrovision copy protection detection on component  
formats (525i, 625i, 525p, and 625p)  
Free-run output mode that provides stable timing when no  
video input is present or video lock is lost  
Arbitrary pixel sampling support for nonstandard video  
sources  
170 MHz conversion rate, which supports RGB input  
resolutions up to 1600 × 1200 at 60 Hz  
Automatic or manual clamp-and-gain controls for  
graphics modes  
32-phase ADC DLL that allows optimum pixel clock  
sampling  
Automatic detection of synchronization source and  
polarity by SSPD block  
Standard identification enabled by STDI block  
RGB that can be color space converted to YCbCr and  
decimated to a 4:2:2 format for video-centric back-end IC  
interfacing  
The SDP has a Macrovision® detection circuit that allows Type I,  
Type II, and Type III Macrovision protection levels. The  
decoder is also fully robust to all Macrovision signal inputs.  
SDP features include:  
Advanced adaptive 3D comb (using the external DDR2  
memory)

Figure 11. Audio Block  
The ADV7850 supports an audio codec comprising a stereo  
ADC and a stereo DAC. A 5:1 stereo mux is placed in front of  
the ADC input. The DAC output is available as a line level  
output and is passed through an internal headphone amplifier.  
The integrated headphone amplifier eliminates the need for an  
external amplifier when driving headphones.  
Figure 12. High Level Overview of Analog Audio Input/Output Configuration  
ANALOG AUDIO MUX FUNCTIONALITY  
A factory calibration is applied during final test to ensure that  
the gain through the mux circuit remains within 5%. Calibra-  
tion is also applied to the ADC reference current to ensure that  
the code swing from the ADC remains within 5% across the  
part for a given input. External impedances with a tolerance of  
1% are required.  
The ADV7850 has five stereo analog audio inputs and one  
stereo analog output. Any one of the stereo inputs can be  
connected to the stereo ADC, and any one of the inputs can be  
connected to the stereo output. In the case of the analog output,  
the ADV7850 also supports mono in-stereo output. The I/O  
connectivity is shown in Table 9.  
AUDIO CODEC FUNCTIONALITY  
The ADV7850 audio codec requires an external MCLK.  
For MCLK with a frequency of 6.144 MHz, 12.288 MHz,  
or 24.576 MHz, the ADC and DAC sample rate is 48 kHz.  
If the MCLK is reduced to 5.6448 MHz, 11.2896 MHz, or  
22.5792 MHz, the ADC and DAC sample rate reduces to  
44.1 kHz.

The bandwidth of the digital filter is sufficient so that 20 kHz  
pass band is maintained in this mode. The 32 kHz sampling is  
also possible but with pass-band reduction.  
The system controller must set an I2C control to select the  
correct mode of operation for the internal PLL so that it always  
generates an internal MCLK of 6.144 MHz. A fixed oversample  
rate of 128× is implemented.

The word depth of both the ADC and DAC is 24 bits. The ADC  
and DAC have independent LRCLK and SCLK signals but use a  
common MCLK.  
The ADC supports I2S mode, providing LRCLK, SCLK, and I2S  
signals. These signals are sent to the HDMI Tx and embedded  
into the HDMI stream.  
The DAC supports I2S mode. The LRCLK, SCLK, and data  
signals must be provided by the back-end SOC and must be  
frequency locked with the MCLK but can be phase independ-  
ent. The output level is 1 V rms full scale.  
The ADV7850 is designed to use a combination of internal and  
external resistances. Measured from the system audio input  
connector, the total nominal input impedance is 32.1 kΩ. All  
analog system audio inputs are designed to support 2.8 V rms  
audio input. Figure 12 shows a high level overview of the  
implementation.  
The input level at the analog audio input pins on the ADV7850  
is 880 mV rms. However, the ADV7850 incorporates a gain  
stage to restore the mux output level to 1.0 V rms. An external  
line driver is required to restore the audio output signals to the  
SCART specification of 2.8 V rms. Analog audio mux output  
signals are inverted with respect to mux input signals.  
There is one stereo headphone amplifier output capable of  
driving 32 Ω loads at 1 V rms. The headphone output  
incorporates circuitry to suppress pop/click sounds during  
power-on/off cycle.
