PACKAGE PINS 40 44 PIN POSITION DIL QFP MATERIAL plastic plastic DESCRIPTION SAA5244A 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 ...
