Video analog input interface
Product specification
TDA8709A
FEATURES
• 8-bit resolution
• Sampling rate up to 32 MHz
• TTL-compatible digital inputs and outputs
• Internal reference voltage regulator
• Low-level AC clock inputs and outputs
• Clamp function with selection for ‘16’ or ‘128’

GENERAL DESCRIPTION
The TDA8709A is an analog input interface for video signal
processing. It includes a an input selector
(one out-of-three video signals), video amplifier with clamp
and external gain control, an 8-bit analog-to-digital
converter (ADC) with a sampling rate of 32 MHz and an
input selector.
APPLICATIONS
• Video signal processing
• Digital picture processing
• Frame grabbing.
• Colour difference signals (U, V)
• R, G, B signals
• Chrominance signal (C).
