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.
