GENERAL 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. The peaking circuit generates asymmetrical overshoots (the amplitude of the `black' overshoots is approximately 2 times higher as the one of the `white' overshoots) and contains a (defeatable) coring function. The RGB control circuit contains a black-current stabilizer circuit with internal clamp capacitors. The white point of the picture tube is adjusted via the I2C-bus. The deflection control circuit provides a drive pulse for the horizontal output stage, a differential sawtooth current for the vertical output stage and an East-West drive current for the East-West output stage.These signals can be manipulated for geometry correction of the picture. The supply voltage for the IC is 8 V. The IC is available in an SDIP package with 52 pins and in a QFP package with 64 pins (see Chapter "Ordering information"). The pin numbers indicated in this document are referenced to the SDIP52; SOT247-1 package; unless otherwise indicated. Janua
