INTEGRATED CIRCUITS DDEAVITCAE SSPEHCIEFIECATTION TDA955X/6X/8X PS/N1 series TV signal processor-Teletext decoder with embedded µ-Controller Tentative Device Specification FVielersuionnd:e1r.
I6ntegrated Circuits, 2000 Jun 22 Previous date: 2000 Apr 06 Philips Semiconductors TV signal processor-Teletext decoder with embedded µ-Controller Tentative Device Specification TDA955X/6X/8X PS/N1 series GENERAL DESCRIPTION The various versions of the TDA955X/6X/8X PS/N1 series combine the functions of a video processor together with a µ-Controller and US Closed Caption decoder.
Several 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 an S-DIP 64 envelope.
The features are given in the following feature list.
The differences between the various ICs are given in the table on page 4.
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.
In the QSS versions without East-West output an AM/FM mode can be activated.
In that case both the QSS amplifier (for AM demodulation) and the FM demodulator are available.
• The mono intercarrier sound circuit has 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.
• The FM-PLL demodulator can be set to centre frequencies of 4.
74/5.
74 MHz so that a second sound channel can be demodulated.
In such an application it is necessary that an external bandpass filter is inserted.
• The QSS amplifier and mono intercarrier sound circuit of some...
