TDA4685 - Video processor

Datasheet Summary

Description

The TDA4685 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 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 eithe.
