Overview
INTEGRATED CIRCUITS DDEAVITCAE SSPEHCIEFIECATTION TDA935X/6X/8X PS/N2 series TV signal processor-Teletext decoder with embedded µ-Controller Tentative Device Specification FVielersuionnd:e2r.
I8ntegrated Circuits, 2001 Jan 18 Previous date: 2000 Nov 29 Philips Semiconductors TV signal processor-Teletext decoder with embedded µ-Controller GENERAL DESCRIPTION The various versions of theTDA935X/6X/8X PS/N2 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.
The ICs have supply voltages of 8 V and 3.
3 V and they are mounted in S-DIP envelope with 64 pins.
The features are given in the following feature list.
The differences between the various ICs are given in the table on page 4.
Tentative Device Specification TDA935X/6X/8X PS/N2 series FEATURES TV-signal processor • 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 intercarrier sound FM demodulator and versions with QSS IF amplifier.
• 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.
• Source selection between ‘internal’ CVBS and external CVBS or Y/C signals • Integrated chrominance trap circuit • Integrated luminance delay line with adjustable delay time • Picture improvement features with peaking (with variable centre frequency and positive/negative overshoot ratio) and black stretching • Integrated chroma band-pass filter with switchable centre frequency • Only one reference (12 MHz) crystal required for the µ-C...
