Overview
The ADC-8032A Analog Composite to SDI Decoder is a 10-bit broadcast quality decoder with a 12-
bit analog to digital converter. It is specifically designed for broadcast or production situations in
which an analog PAL, PAL-M, PAL-N, or NTSC composite signal must be converted to a component
SDI signal. Four SDI outputs are provided. The ADC-8032A fits into the Ross 8000 series digital
frames, with four cards in the DFR-8104A (1RU), and up to ten cards in the DFR-8110A (2RU).
Please refer to the frame User Manual for specific ventilation and cooling instructions to maintain
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.
