Description
The TDA4687 is a monolithic integrated circuit with a luminance and a colour difference interface for video processing in TV receivers.
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.
