Product specification
Video analog input interface
TDA8708A
FEATURES
8-bit resolution
Sampling rate up to 32 MHz
Binary or two's complement 3-state TTL outputs
TTL-compatible digital inputs and outputs
Internal reference voltage regulator
Power dissipation of 365 mW (typical)
Input selector circuit (one out of three video inputs)
Clamp and Automatic Gain Control (AGC) functions for
CVBS and Y signals
No sample-and-hold circuit required.
The TDA8708A has white peak control in modes 1 and
2 whereas the TDA8708B has control in mode 1 only.
APPLICATIONS
Video signal decoding
Scrambled TV (encoding and decoding)
Digital picture processing
Frame grabbing.
GENERAL DESCRIPTION
The TDA8708A is an analog input interface for video signal
processing. It includes a video amplifier with clamp and
gain control, an 8-bit analog-to-digital converter (ADC)
with a sampling rate of 32 MHz and an input selector.
