DESCRIPTION
The Integrated VIP and Teletext (IVT1.1) is a teletext
decoder (contained within a single-chip package) for
decoding 625-line based World System Teletext
transmissions. The teletext decoder hardware is based on
a reduced function version of the device SAA5246
(IVT1.0).
The Video Input Processor (VIP) section of the device
uses mixed analog and digital designs for the data slicer
and the display clock phase-locked loop functions. As a
result the number of external components is greatly
reduced and no critical or adjustable components are
required. A single page static RAM is incorporated in the
device thereby giving a genuine single-chip teletext
decoder device.
