GENERAL DESCRIPTION
The SAA526xPS ICs are single-chip 10-page 625-line
World System Teletext (WST) decoders with a high level
command interface, SAFARI compatible.
It has been designed so that the overall system cost is kept
to a minimum. This has been achieved through the
capability of the device to be driven from a single +5 V
power supply, low cost 12 MHz crystal oscillator and the
high level command interface, which offers the benefit of
low software overhead in the TV microcontroller.
The SAA526xPS offers automatic detection of Fastext or
TOP transmissions. The device also incorporates a facility
to detect the pages in the transmission, which allows only
transmitted pages to be selected by page-up and
page-down.
SAA5262 and SAA5263 provide Automatic Channel
Installation (ACI) information.
SAA5263 provides access to Electronic Programme Guide
(EPG) information.

HIGH LEVEL COMMAND INTERFACE
The I2C-bus interface is used to pass control commands and data between the SAA526xPS and the television
microcontroller. The interface uses high level commands, which are backward compatible with the SAFARI interface.
