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-Controller, Teletext- and the colour decoder • PAL/NTSC or multi-standard colour decoder with automatic search system • Internal base-band delay line • RGB control circuit with ‘Continuous Cathode Calibration’, white point and black level offset adjustment so that the colour temperature of the dark and the light parts of the screen can be chosen independently. • Linear RGB or YUV input with fast blanking for external RGB/YUV sources. The Text/OSD signals are internally supplied from the µ-Controller/Teletext decoder • Contrast reduction possibility during mixed-mode of OSD and Text signals • Horizontal synchronization with two control loops and alignment-free horizontal oscillator • Vertical count-down circuit • Vertical driver optimized for DC-coupled vertical output stages • Horizontal and vertical geometry processing • Horizontal and vertical zoom function for 16 : 9 applications • Horizontal parallelogram and bow correction for large screen picture tubes • Low-power start-up of the horizontal drive circuit 2001 Jan 18 2 Philips Semiconductors TV signal processor-Teletext decoder with embedded µ-Controller Tentative Device Specification TDA935X/6X/8X PS/N2 series µ-Controller • 80C51 µ-controller core standard instruction set and timing • 1 µs machine cycle • 32 - 128Kx8-bit late programmed ROM • 3 - 12Kx8-bit Auxiliary RAM (shared with Display and Acquisition) • Interrupt controller for individual enable/disable with two level priority • Two 16-bit Timer/Counter registers • One 16 bit Timer with 8-bit Pre-scaler • WatchDog timer • Auxiliary RAM page pointer • 16-bit Data pointer • Stand-by, Idle and Power Down (PD) mode • 14 bits PWM for Voltage Synthesis Tuning • 8-bit A/D converter • 4 pins which can be programmed as general I/O pin, ADC input or PWM (6-bit) output Data Capture • Text memory for 0, 1 or 10 pages • In the 10 page versions inventory of transmitted Teletext pages stored in the Transmitted Page Table (TPT) and Subtitle Page Table (SPT) • Data Capture for US Closed Caption • Data Capture for 525/625 line WST, VPS (PDC system A) and Wide Screen Signalling (WSS) bit decoding • Automatic selection between 525 WST/625 WST • Automatic selection between 625 WST/VPS on line 16 of VBI • Real-time capture and decoding for WST Teletext in Hardware, to enable optimized µ-processor throughput • Automatic detection of FASTEXT transmission • Real-time packet 26 engine in Hardware for processing accented, G2 and G3 characters • Signal quality detector for video and WST/VPS data types • Comprehensive teletext language coverage • Full Field and Vertical Blanking Interval (VBI) data capture of WST data Display • Teletext and Enhanced OSD modes • Features of level 1.5 WST and US Close Caption • Serial and Parallel Display Attributes • Single/Double/Quadruple Width and Height for characters • Scrolling of display .
