TDA8758 - YC 8-bit low-power analog-to-digital video interface

Description

The TDA8758 is an 8-bit video high-speed low-power analog-to-digital conversion (ADC) interface for YC and CVBS signal processing.

It converts 1-of-3 CVBS input signals or 1-of-2 YC input signals into binary or two’s complement words at a sampling rate of 32 MHz.

Features

  • Two 8-bit ADCs:.
  • one Luminance or CVBS channel.
  • one Chrominance channel.
  • Sampling rate up to 32 MHz.
  • Binary or two's complement 3-state TTL outputs for each channel.
  • Internal reference voltage regulator.
  • TTL-compatible digital inputs and outputs.
  • Power dissipation of 530 mW (typical).
  • Input selector circuit (five selectable video inputs for CVBS or YC processing).
  • Peak white enable input.
  • Clamp an.
