TDA8376

` Source selection with 2 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
` Video identification circuit which is independent of the synchronization for stable On Screen Display (OSD) under 'no-signal' conditions
` Integrated chrominance trap with pre-shoot compensation and bandpass filters (automatically calibrated)
` Integrated luminance delay line
` Asymmetrical peaking in the luminance channel with a (defeatable) noise coring function
` Black stretcher circuit in the luminance channel
` PAL/NTSC colour decoder with automatic search system
` Easy interfacing with the TDA8395 (SECAM decoder) for multistandard 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 depends on the white point adjustment
` Two linear RGB inputs and fast blanking
` Horizontal synchronization with two control loops and alignment-free horizontal oscillator
` Vertical count-down circuit
` Geometry correction by modulation of the vertical and E-W drive
` Vertical and horizontal zoom possibility for 16 : 9 applications (TDA8376A only)
` I2C-bus control of various functions
` Low dissipation (700 mW)
` Small amount of peripheral components compared with competition ICs
` Y, U and V inputs and outputs.

The TDA8376 and TDA8376A are alignment-free I²C-bus controlled video processors which contain a PAL/NTSC colour decoder, luminance processor, sync processor, RGB-control and deflection processor. The circuits have been designed for use with the baseband chrominance delay line TDA4665 and for DC-coupled vertical and East-West (E-W) output stages. Both ICs are pin compatible. The TDA8376A has a flexible horizontal and vertical zoom possibility for 16 : 9 applications.

The supply voltage for the ICs is 8 V. The ICs are available in an SDIP package with 52 pins and in a QFP package with 64 pins (see Chapter 4).
