optimum operating conditions. This card also fits into Leitch* FR-6800 series frames to provide you
with greater installation versatility. The ADC-8032A is available in two different models:
* Leitch is a trademark of Leitch Technology Corporation
ADC-8032A User Manual (Iss. 04)
Introduction • 1-1
•
•
ADC-8032A - The base model decoder includes Proc Amp, Line Delay, and Line
Synchronizer timing modes.
ADC-8032A-S - The “S” model includes a Frame Synchronizer, along with all the
features available on the ADC-8032A
The ADC-8032A-S version comes with a fully functional frame synchronizer, capable of
synchronizing incoming video to house reference. Various timing modes are available to
accommodate most situations. New techniques in frame synchronization contribute to the board’s low
power requirements and compact design. The complete circuit for the ADC-8032A, including a 12-bit
A-D converter, decoder, frame (or line) synchronizer, serializer, TTL tracking delay pulse, and
microprocessor is contained on a single DA-sized card. Additional daughter cards are not required.
A rich set of features is instantly accessible using simple card-edge switches and controls in
conjunction with a concise Heads-Up Display. The ADC-8032A’s 10-bit decoding process provides
excellent performance with all types of picture sources. In order to achieve the highest level of
precision, all signal processing and decoding is performed entirely in the digital domain. The decoder
uses a very sophisticated 5-line comb filter with advanced adaptive control algorithms.
To make configuration simple and easy, the ADC-8032A offers a Heads-Up Display mode for most
board-level adjustments. This display is especially convenient during setup, and for programming
several ADC-8032A cards with identical configurations. With the display enabled, the parameter
currently being adjusted has its value super-imposed over all board outputs. As an alternative to the
Heads-up Display, the board’s Comlink Terminal Display allows you to view all settings
simultaneously on any PC running VT-100 terminal emulation. The only requirement is a connection
between the PC’s serial port and the ADC-8032A’s Comlink connector. This feature is especially
convenient for making adjustments while the card’s output is on air.
The ADC-8032A and the ADC-8032A-S decoders are part of a full line of RossGear digital
distribution products engineered to satisfy the highest quality broadcast standards and the most
demanding requirements of your facility.

Operating Conventions For Function Tables
The following rules apply to the function tables that are used throughout this section:
•
•
•
•
The label “ + ” instructs you to toggle the Mode Select switch (SW2) up
momentarily.
The label “ - ” instructs you to toggle the Mode Select switch (SW2) down
momentarily.
The label “ + (h) ” instructs you to hold the Mode Select switch (SW2) up for one
second.
The label “ - (h) ” instructs you to hold the Mode Select switch (SW2) down for one
second.
Selecting Banks
Function Select switch functionality is divided into three banks of functions. Use the following steps
to select Bank A, B or C as required.
1. Rotate Function Select (SW1) to position 0. Note that position 0 is always used to
select the bank, regardless of the bank that you are currently using.
2. Toggle Mode Select (SW2) up or down to choose the desired bank. Three positions
are available: Bank A, B or C.
3. The table below illustrates each switch function, along with the Heads-Up Display
label, the Status LED indication, and the default value. If you are not using a
display, be sure to verify your selection on the Status LED's.

About the Timing Mode
Timing Mode Summary
Bank C-1: Timing Mode Procedure
About the Timing Mode
There are two versions of the ADC-8032A available. The standard ADC-8032A can be timed within
one line in 37ns increments. The ADC-8032A-S with the frame synchronizer can be timed within one
video frame in 37ns increments. The fine phase potentiometer (RV1) is provided for sub-pixel
adjustment.
The presence of a frame synchronizer means that the Frame Delay and Frame Sync modes are
available. Without the frame synchronizer, the Line Delay and Line Sync modes are available.
Looking at it another way, the S version provides a full frame of memory, whereas the non-S version
provides a few lines of memory. This means that the non-S version provides enough timing flexibility
to meet a wide variety of applications. It also means that these cards can be upgraded in the field for
full frame synchronizing capabilities. The following information provides detailed explanations of
when to use each mode, as well as an analysis of the advantages each mode has to offer.
Line Delay (ADC-8032A & ADC-8032A-S)
Line Delay mode uses the input signal to generate the output timing. In other words, it provides a
constant delay between the input and the output. The external reference is not used in any way. This
is useful in applications where a constant delay through the card is required.
The delay through the card has a minimum value, as described in Chapter 7, “Specifications”. Output
timing can be adjusted from this minimum delay up to an additional two lines in sub-pixel increments.
ADC-8032A User Manual (Iss. 04)
Using Banks • 4-13
Line Sync (ADC-8032A & ADC-8032A-S)
Line Sync mode uses the external reference to generate the output timing on a line-by-line basis, but
uses the input signal timing to decide when a frame begins.
Whenever a signal is received, the output-timing generator waits for the next falling edge of H Sync
on the external reference before displaying the incoming line. The advantage of this mode is that as
long as all input sources are timed to be on the same line, the output timing stays constant, regardless
of which input is selected. This is very useful in that all sources to the ADC-8032A (for example,
from a routing switcher) only need to be lined up to the same line.
The Line Sync mode has internal latency, so that using minimum delay still means that the output
video will not be lined up with the external reference. To do so would have added even more latency,
which would not be desirable. However, output timing can be delayed by up to two lines from the
minimum delay point on, in sub-pixel increments, so that the output video can be lined up as required.
If two input sources are not on the same line, then switching
from one source to the other causes a jump in the output timing
by an exact number of lines. For example, if the two sources
are 2.5 lines apart, the output will jump by either 2 or 3 lines
depending on the position of the sources with respect to the
external reference.
Note
Threshold Point
As the input signal is delayed in time, there comes a point where the output timing will have to jump
by exactly one line (the output must always come after the input). This point is called the threshold
point. When comparing the input signal with the external reference, the threshold point is 4.25
microseconds before the falling edge of the external reference. In other words, if the input signal’s
falling H sync edge is 4.25 microseconds before the external reference’s falling H sync edge, the input
signal is said to be on the threshold point.
In addition, there is built in hysteresis so that if an input source is on the threshold point, the output
timing will be constant and will not jump back and forth by a line if the input signal varies slightly.
However, if the input signal is exactly on the threshold point, the output timing may vary from one
power up sequence to the other. In other words, the card may power up with different timing than the
previous time it was powered-up. To avoid this condition, it is recommended to keep the input signal
away from the threshold point. One microsecond can be considered a safe distance.
In Line Sync mode, you must keep the falling H sync edge of
Note
the incoming video away from the threshold point.
Frame Delay (ADC-8032A-S)
The Frame Delay mode is identical to the Line Delay mode, except that the output timing can be
delayed by up to a full frame of video. By using almost a full frame of delay, it is possible to set
apparent negative timing, making it look like the output occurs before the input, although delayed by 1
frame.
Frame Sync (ADC-8032A-S)
The Frame Sync mode makes it possible to use asynchronous sources. The output timing is generated
entirely based on the external reference. Whether a synchronous or an asynchronous source is used,
output timing is constant. The delay through the card will be the minimum latency (in the order of
microseconds) to a full frame of delay.

It is recommended that the Hotswitch Mode and Input Loss Mode
be set the same with either: both set to freeze, or both set to black.
There is circuitry in the sync stripper that removes unwanted
impulses to make the circuit more noise tolerant. During a
hotswitch, this could cause the ADC-8032A to interpret the signal
has been lost. Since the Input Loss mode overrides the Hotswitch
mode setting, having one set to freeze and the other set to black
could lead to a momentary glitch on the screen.
Important
Bank C-B: Hotswitch Mode
The ADC-8032A uses a phase-locked-loop (PLL) to synchronize its pixel clock to the incoming
signal’s line rate. Because of this, any disturbance to the incoming line rate, such as an untimed
switch outside the lock window of the PLL, will cause the PLL to lose lock. It can take several fields
before the PLL can regain lock, and until it does so, the decoder cannot properly decode the incoming
video. The result is that untimed switches will result in a disruption to the output video.
To mask this disruption, a hotswitch mode was created. This is accomplished by momentarily freezing
the last good frame, or momentarily going to black while the untimed switch occurs. Going to black is
recommended since the output can be forced to black as soon as the hotswitch condition is detected.
Freezing must wait until the next field, in which case a single corrupted field could get through to the
output.
In Frame Sync, the output timing will be undisturbed as it is based on the external reference. In Line
Sync mode, as long as the input sources are on the same line relative to the external reference, and
they do not cross the threshold point (see Bank C-1 Timing Mode for details on the threshold point),
4-20 • Using Banks
ADC-8032A User Manual (Iss. 04)
then the output timing will also be undisturbed. In all other cases, the output timing will be disturbed
any time an untimed switch is made at the input of the ADC-8032A. This function sets the mode or
disables it. Three choices are available:
•
•
Off - disables the Hotswitch Mode.
Black - the output momentarily cuts to black when an untimed switch is made at the
input.
•
Freeze - (ADC-8032A-S only) the last valid image is momentarily frozen. The
freeze will affect either field 1, field 2 or the entire frame (as determined by the
Freeze Mode function).
In either case, the output returns once the card has synchronized to the input. Use the following steps
to set the Hotswitch Mode:
1. Select Bank C, and rotate Function Select to position B.
2. Select the desired mode according to the table below:
•
•

Freeze hotswitching is not supported in Line Delay, Line Sync
and Frame Delay timing modes. If one of these timing modes
is selected and freeze hotswitching is enabled, the hotswitch
will go to black instead.
Note
Because output timing is disrupted in Line Delay and Frame
Delay modes, hotswitching is not guaranteed to go completely
black. These two timing modes should never be used if the
input source is switched while on air, since the output timing
will be affected, and this could affect equipment downstream of
the ADC-8032A.

Details
Overview
The SMPTE 269M Fault Reporting system, also known as an SMPTE “alarm”, provides indication if
one or more frame modules encounter a fault or an abnormal condition. The ADC-8032A module
provides a jumper to enable SMPTE-269M fault reporting. The card connects by means of an internal
interface circuit to an auxiliary telco connector on RossGear 8000 series frames. When the frame
connection is interfaced with a customer-designed system of LEDs or audible alarms, faults can be
traced to a specific frame when a card fault occurs within that frame.
The following diagram illustrates a general arrangement for SMPTE 269M alarm reporting:
Figure 5. SMPTE 269M Alarm Reporting: Internal interface and typical connections
ADC-8032A User Manual (Iss. 04)
SMPTE 269M Alarm Reporting • 5-1
Jumper Setup
If fault reporting for the ADC-8032A is desired, use jumper JP4 - 269M Fault Report to set up the
card.
1. To access the jumper, remove the card from the frame by pressing down the white
card ejector tab and pulling the card from the frame slot.
2. Observing all static discharge and handling precautions, place the card with the
component side facing up on a clean flat surface.
3. To enable SMPTE fault reporting, set jumper JP4 to EN position. See the Jumper
Setup section in Chapter 2 “Installation and Setup”.
4. To disable SMPTE fault reporting, set jumper JP4 to DIS position. See the Jumper
Setup section in Chapter 2 “Installation and Setup”.
5. To return the card to the designated frame installation slot, hold the ADC-8032A
card by the edges and carefully align the card edges with the slots in the frame. Then
fully insert the card into the frame until the rear connection plug is properly seated.
Frame Connections
The SMPTE 269M Fault Reporting connection on RossGear 8000 series frames is provided by the
auxiliary telco connector, AUX A, for interfacing with a customer-designed alarm system.
Aux A Connectors for
SMPTE 269M Fault Reporting
Figure 6. SMPTE 269M Alarm Reporting Frame Connections
Connect the frame’s AUX A connector to your facility’s SMPTE alarm circuit.
Details
The fault report contacts are closed when the card detects an internal failure or a power loss condition.
Some internal failures are:
•
•
•
Failure of the card to initialize
Failure in the fault reporting circuitry
Failure to detect a valid analog input signal to the card

Overview
Cable Construction
Connection and Configuration
Overview
The board’s Terminal Display feature uses the Comlink BNC (7) to establish a connection between a
PC and the ADC-8032A. When properly connected, you can view your setup parameters on a PC
running VT-100 terminal emulation. All tables are output in ASCII format using an RS-485 interface.
Because of the nature of the frame, it is not possible to have a true differential signal. In this situation,
using a BNC on the frame side, the connection is single-ended. Only the center conductor carries
information, while the shield is grounded.
Ensure that the PC and the card frame are at the same ground
potential in order to avoid ground loops.
Important!
Although the interface is RS-485, the Comlink can function with most modern RS-232 equipment,
thereby making it easy and convenient to use with standard PC COM ports. To connect the Comlink
between the ADC-8032A and your PC, you require a coax adapter cable with a BNC connector at one
end, and either a 9-pin or 25-pin RS-422 or RS-232 connector at the other end.
ADC-8032A User Manual (Iss. 04)
Comlink • 6-1
Cable Construction
Construct a custom coax cable adapter as follows:
•
•
On the Frame end of the coax cable, no change to the BNC cable is required. Ensure
that the pin and shield are properly connected.
On the PC end of the cable, make the following connections according to whether your
PC port uses a 9-pin “D” or a 25-pin “D” connector:
Regardless of whether your PC port uses a 9-pin “D” or a 25-pin
“D” connector, the pin-out configuration may vary. Always check
your PC’s Technical Guide to determine the correct pin-outs for
your computer. The RX and GND pin-outs will vary from
machine to machine.
Important!

Connection and Configuration
Once you have constructed the Comlink adapter cable, connect it and configure the PC as follows:
1. Connect the cable between your PC’s serial port and BNC 7 on the rear panel of the
ADC-8032A.
2. With the custom cable properly connected, set up your PC’s serial port parameters as
follows:
•
•
•
•
•
19.2 K baud rate
8 data bits
No parity
1 stop bit
No flow control
3. On your PC, run a program that uses VT-100 terminal emulation, such as
Terminal.exe or HyperTerminal. With the ADC-8032A powered up, you should
now have all setup parameters visible on the PC, as illustrated in the sample screen
below.
