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:
The SAA5265 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.
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).
