Product specification
TDA8708B
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.
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.
