Overview
INTEGRATED CIRCUITS DATA SHEET SAA5254 Integrated VIP and teletext decoder (IVT1.
1X) Preliminary specification Supersedes data of July 1993 File under Integrated Circuits, IC02 1996 Nov 07 Philips Semiconductors Preliminary specification Integrated VIP and teletext decoder (IVT1.
1X) FEATURES • Complete teletext decoder including page memory and FASTEXT links in a 40-pin DIP package • Automatic processing of extension packet 26 for widest possible language decoding.
All our standard language options can be available, and language option is readable via I2C-bus • 100% hardware compatible with the SAA5244A; plug-in replacement and extra market • 100% hardware compatible with the SAA5244A, except if the special OSD symbols were used with the SAA5244A, except ROM identification number • The device is pin-aligned with the other members of the new Philips teletext decoder family, i.
e.
SAA5280 and the SAA5249, making one hardware solution for the full range • Low software overhead for the control microprocessor • Single page acquisition system • RGB interface to standard colour decoder ICs, push-pull output drive • Separate text and video signal quality detectors.
ORDERING INFORMATION TYPE NUMBER SAA5254P PACKAGE NAME DIP40 DESCRIPTION plastic dual in-line package; 40 leads (600 mil) SAA5254 DESCRIPTION The Integrated VIP and Teletext decoder (IVT1.
1X) is designed to decode 625-line based World System Teletext transmissions.
This single-chip teletext decoder hardware is based on the SAA5244A with which it is completely compatible.
Like the SAA5244A the device contains all the hardware necessary to decode the teletext, but the SAA5254 also contains extra hardware to process the extension packet 26 characters automatically, extending the markets to which the TV chassis can be shipped and opening the possibility of many more language options.
