I6ntegrated Circuits, Previous version: 2000 Apr 06 Philips Semiconductors TV signal processor-Teletext decoder with embedded µ-Controller Tentative Device Specification TDA955X/6X/8X H/N1 series GENERAL DESCRIPTION The various versions of the TDA955X/6X/8X H/N1 series combine the functions of a video 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 www.

vcoemrs with 90° and 110° picture tubes.
The ICs have supply voltages of 8 V and 3.
3 V and they are mounted in a QFP 80 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 • The QSS and mono FM functionality are both available so that an FM/AM TV receiver can be built without the use of additional ICs • 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 vision IF and mono intercarrier sound circuit can be used for the demodulation of FM radio signals • Video switch with 2 external CVBS inputs and a CVBS output.
One of the CVBS inputs ca...
