TDA9381PS PDF – TV Signal Processor, DIP 64 ( TDA9381 )

Part Number: TDA9381PS, TDA9381

Function: TV signal processor

Package: DIP 64 Pin type

Manufacturer: Philips Semiconductor





This is TV signal processor-Teletext decoder with embedded µ-Controller.

The various versions of the TDA9381PS series combine 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. The ICs are intended to be used in economy television receivers with 90° and 110° picture tubes.

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

7. Integrated luminance delay line with adjustable delay time
