DESCRIPTION
The STV5345is a HCMOS integratedcircuit which
performsall the processingof logical data within a
625 linessystem teletextdecoder.It is designedto
operate inconjunctionwith one-chip:theSAA5231
integratedchip which extracts Teletext information
embedded in a composite video signal. Up to 8
pages of display data can be stored in internal
memory. Using 8Kbytes of external memory leads
to a 16 pages application.A completesystem also
comprises a microprocessor controlling the
STV5345via a2-wires serial bus.Anon-chipROM
memory containsthecharactersets. TheSTV5345
performs automatic selection of one of up to six
natural languages.Data bytes maybe decodedin
either 7-Bit plus parity or in full 8-Bit formats. The
chip set also supports facilities for reception and
display of higher-levelprotocol data.
