General 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.

with the multistandard decoder TDA4655 or TDA9160 plus delay line TDA4661 and the Picture Signal Improvement (PSI) IC, TDA467X, or from a

INTEGRATED CIRCUITS DATA SHEET TDA4685 Video processor with automatic cut-off control Product specification Supersedes data of May 1993 File under Integrated Circuits, IC02 1997 Jun 20 Philips Semiconductors Product.

Key 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.
