TDA4689 - Video processor

Datasheet Summary

Description

The TDA4689 is a monolithic integrated circuit with a luminance and a colour difference interface for video processing in TV receivers.

Its primary function is to process the luminance and colour difference signals from a colour decoder which is equipped e.g.

Features

  • Operates from an 8 V DC supply.
  • Black level clamping of the colour difference, luminance and RGB input signals with coupling-capacitor for DC level storage.
  • Two analog RGB inputs, selected either by fast switch signals or via I2C-bus; brightness and contrast control of both RGB inputs.
  • Saturation, contrast, brightness and white adjustment via I2C-bus.
  • Same RGB output black levels for Y/CD and RGB input signals.
  • Timing pulse generation from e.
