Preliminary specification
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).
