TDA8708A
FEATURES
- 8-bit resolution
- Sampling rate up to 32 MHz
- Binary or two's plement 3-state TTL outputs
- TTL-patible digital inputs and outputs
- Internal reference voltage regulator
- Power dissipation of 365 m W (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
- 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.
