28 leads GENERAL DESCRIPTION TDA4681 The TDA4681 is a monolithic integrated circuit with a colour difference interface for video processing in TV

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 fully-controlled, analog RGB inputs, selected either by fast switch signals or via I2C-bus.
  • Saturation, contrast and brightness adjustment via I2C-bus.
  • Same RGB output black levels for Y/CD and RGB input signals.
  • Timing pulse generation from either a 2 or 3-level sandcastle pulse for cla.
