TDA8361 Overview
The TDA8360, TDA8361 and TDA8362 are single-chip TV processors which contain nearly all small signal functions that are required for a colour television receiver. For a plete receiver the following circuits need to be added: a base-band delay line (TDA4661), a tuner and output stages for audio, video and horizontal and vertical deflection.
TDA8361 Key Features
- Vision IF amplifier with high sensitivity and good differential gain and phase
- Multistandard FM sound demodulator (4.5 MHz to 6.5 MHz)
- Integrated chrominance trap and bandpass filters (automatically calibrated)
- Integrated luminance delay line
- RGB control circuit with linear RGB inputs and fast blanking
- Horizontal synchronization with two control loops and alignment-free horizontal oscillator without external ponents
- Vertical count-down circuit (50/60 Hz) and vertical preamplifier
- Low dissipation (700 mW)
- Small amount of peripheral ponents pared with petition ICs
- Only one adjustment (vision IF demodulator)
TDA8361 Applications
- Alignment-free PAL colour decoder for all PAL standards, including PAL-N and PAL-M. TDA8361
- PAL/NTSC colour decoder with automatic search system
- Source selection for external audio/video (A/V) inputs (separate Y/C signals can also be applied). TDA8362
