Preliminary specification
Integrated VIP and teletext decoder
(IVT1.1X)
SAA5254
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 I
2
C-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.
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.
