TDA9382 Overview
The various versions of theTDA935X/6X/8X PS/N2 series bine the functions of a TV signal processor together with a µ-Controller and US Closed Caption decoder. Most versions have a Teletext decoder on board. The Teletext decoder has an internal RAM memory for 1or 10 page text.
TDA9382 Key Features
- Multi-standard vision IF circuit with alignment-free PLL demodulator
- Internal (switchable) time-constant for the IF-AGC circuit
- A choice can be made between versions with mono
- The mono intercarrier sound versions have a selective FM-PLL demodulator which can be switched to the different FM sound
- Source selection between ‘internal’ CVBS and external CVBS or Y/C signals
- Integrated chrominance trap circuit
- Integrated luminance delay line with adjustable delay
- Picture improvement features with peaking (with variable centre frequency and positive/negative overshoot ratio) and bla
- Integrated chroma band-pass filter with switchable centre frequency
- Only one reference (12 MHz) crystal required for the µ-Controller, Teletext- and the colour decoder
TDA9382 Applications
- Horizontal parallelogram and bow correction for large screen picture tubes
