General 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.
Key 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.
