Multi page intelligent teletext decoder
Product specification
SAA5360; SAA5361
1 FEATURES
• Support for 50 or 60 and 100 or 120 Hz and progressive
scan display modes
• 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)

using teletext and dedicated menu icons
• Video Programming System (VPS) decoding
• Wide Screen Signalling (WSS) decoding
• SAA5360 supports Pan-European, Arabic and Iranian
character sets
• SAA5361 supports Pan-European, Cyrillic, Greek and
Arabic character sets
• 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

5 V tolerant
• Single 12 MHz crystal oscillator
• Single power supply: from 3.0 V to 3.6 V
• Operating temperature: −20 to +70 °C
• 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.
2 GENERAL DESCRIPTION
The SAA5360; SAA5361 is a single-chip multi page 625
line world system teletext decoder with a high-level
command interface, and is SAFARI compatible.
The device is 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 SAA5360 incorporates the following functions:
• 10 page teletext decoder with OSD, fastext, TOP,
default and list acquisition modes
• Automatic channel installation support.
The functionality of the SAA5361 is similar to the
SAA5360, but offers the capability to store up to
250 additional pages of teletext in an external SRAM.
