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).
