TDA8366 Description
TDA8366 The TDA8366 is an I2C-bus controlled PAL/NTSC TV processor. The circuit has been designed for use with the baseband chrominance delay line TDA4665 and for DC-coupled vertical and East-West (EW) output stages. The device can process both CVBS and Y/C input signals and has a linear RGB-input with fast blanking.
TDA8366 Key Features
- Multistandard vision IF circuit (positive and negative modulation)
- Video identification circuit in the IF circuit which is independent of the synchronization for stable On Screen Display
- Source selection with 2 Colour Video Blanking Synchronization (CVBS) inputs and a Y/C (or extra CVBS) input
- Output signals of the video switch circuit for the teletext decoder and a Picture-In-Picture (PIP) processor
- Integrated chrominance trap and bandpass filters (automatically calibrated)
- Integrated luminance delay line
- Asymmetrical peaking in the luminance channel with a (defeatable) noise coring function
- PAL/NTSC colour decoder with automatic search system
- Easy interfacing with the TDA8395 (SECAM decoder) for multistandard
TDA8366 Applications
- RGB control circuit with black-current stabilization and white point adjustment; to obtain a good grey scale tracking the black-current ratio of the 3 guns depe
