描述 Description

GENERAL DESCRIPTION
The TDA8708B 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.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 TDA8708B has no white peak control in mode 2  whereas the TDA8708A has control in modes 1 and 2
• In-range output (not TTL levels).APPLICATIONS
• Video signal decoding
• Scrambled TV (encoding and decoding)
• Digital picture processing
• Frame grabbing.
