2 / 24 page 2000 Jan 27 2 Philips Semiconductors Preliminary specification 10 and 1 page intelligent teletext decoders SAA5264; SAA5265 FEATURES The following features apply to both SAA5264 and SAA5265: • Complete 625 line teletext decoder in one chip reduces printed circuit board area and cost • Automatic detection of transmitted fastext links or service information (packet 8/30) • On-Screen Display (OSD) for user interface menus using teletext and dedicated menu icons • Video Programming System (VPS) decoding • Wide Screen Signalling (WSS) decoding • Pan-European, Cyrillic, Greek/Turkish and French/Arabic character sets in each chip • High-level command interface via I2C-bus gives easy control with a low software overhead • High-level command interface is backward compatible to Stand-Alone Fastext And Remote Interface (SAFARI) • 625 and 525 line display • RGB interface to standard colour decoder ICs, current source • Versatile 8-bit open-drain Input/Output (I/O) expander, 5 V tolerant • Single 12 MHz crystal oscillator • 3.3 V supply voltage. SAA5264 features • Automatic detection of transmitted pages to be selected by page up and page down • 8 Page fastext decoder • Table Of Pages (TOP) decoder with Basic Top Table (BTT) and Additional Information Tables (AITs) • 4 Page user-defined list mode. GENERAL DESCRIPTION The SAA5264 is a single-chip ten page 625-line World System Teletext decoder with a high-level command interface, and is SAFARI compatible. The SAA5265 is a single-chip one page version of the SAA5264. Both devices are designed to minimize the overall system cost, due to the high-level command interface offering the benefit of a low software overhead in the TV microcontroller. The SAA5264 has the following functionality: • 10 page teletext decoder with OSD, Fastext, TOP, default and list acquisition modes • Automatic channel installation support • Closed caption acquisition and display • Violence Chip (VChip) support. The SAA5265 has the following functionality: • 1 Page teletext decoder with OSD, fastext and default acquisition modes • Automatic channel installation support • Closed caption acquisition and display • VChip support • No EEPROM fitted (there is no list mode feature). |
