Overview
INTEGRATED CIRCUITS DATA SHEET TDA8708A Video analog input interface Product specification Supersedes data of April 1993 File under Integrated Circuits, IC02 June 1994 Philips Semiconductors Philips Semiconductors Product specification Video analog input interface 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.
GENERAL DESCRIPTION APPLICATIONS • Video signal decoding TDA8708A • Scrambled TV (encoding and decoding) • Digital picture processing • Frame grabbing.
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.
