INTEGRATED CIRCUITS DDEAVITCAE SSPEHCIEFIECATTION TDA955X/6X/8X H/N1 series TV signal processor-Teletext decoder with embedded µ-Controller Tentative Device Specification 2000 Jun 22 FVielersuionnd:e1r.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.DataShereet4cUei.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 can be used as Y/C input. • 2 external audio inputs. The selection of the various inputs is coupled to the selection of the CVBS signals • Integrated chrominance trap circuit • Integrated luminance delay line with adjustable delay time • Switchable group delay correction in the CVBS path • Picture improvement features with peaking (with switchable centre frequency, depeaking, variable positive/negative overshoot ratio and video dependent coring), dynamic skin tone control and blue-, black- and white stretching • Integrated chroma band-pass filter with switchable centre frequency • Switchable DC transfer ratio for the luminance signal • Only one reference (12 MHz) crystal required for the µ-Controller, Teletext- and the colour decoder • PAL/NTSC or multi-standard colour decoder with automatic search system • Internal base-band delay line • Indication of the Signal-to-Noise ratio of the incoming CVBS signal • A linear RGB/YUV/YPBPR input wit […]
