DESCRIPTION
The SAA5246A is a single-chip teletext decoder IC for
decoding 625 line base World System Teletext
transmissions. The teletext decoder hardware is based on
the Enhanced Computer Controlled ECCT device
(SAA5243) with some additional features.
The Video Input Processor section of the device uses
mixed analog and digital designs in the data slicer and
clock phase-locked-loop functions. As a result the number
of external components are greatly reduced and no critical
or adjustable components are required.
