DESCRIPTION

The STV5345 is a HCMOS integrated circuit which

performs all the processing of logical data within a

625 lines system teletext decoder. It is designed to

operate in conjunction with one-chip : the SAA5231

integrated chip 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 complete system also

comprises a microprocessor controlling the

STV5345 via a 2-wires serial bus. An on-chip ROM

memory contains the character sets. The STV5345

performs automatic selection of one of up to six

natural languages. Data bytes may be decoded in

either 7-Bit plus parity or in full 8-Bit formats. The

chip set also supports facilities for reception and

display of higher-level protocol data.
