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).
