Description

The SAA526xPS ICs are single-chip 10-page 625-line World System Teletext (WST) decoders with a high level command interface, SAFARI compatible.

SAA526xPS 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, SAA526xPS 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.
