Description
The various versions of the TDA9381 series combine the functions of a TV signal processor together with a m-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. The ICs are intended to be used in economy television receivers with 90° and 110° picture tubes.
Features
1. TV-signal processor
(1) Multi-standard vision IF circuit with alignment-free PLL demodulator
(2) Internal (switchable) time-constant for the IF-AGC circuit
(3) A choice can be made between versions with mono intercarrier sound FM demodulator and versions with QSS IF amplifier.
(4) The mono intercarrier sound versions have a selective FM-PLL demodulator which can be switched to the different FM sound frequencies (4.5/5.5/6.0/6.5 MHz). The quality of this system is such that the external band-pass filters can be omitted.
(5) Source selection between ‘internal’ CVBS and external CVBS or Y/C signals
(6) Integrated chrominance trap circuit
