STV224X, STV228X, STV223X - GENERAL DESCRIPTION
1 GENERAL DESCRIPTION
1.1 INTRODUCTION
The STV224XH/228XH/223XH are fully bus-controlled ICs for TV that include PIF, SIF, Luma, Chroma
and Deflection processing functions. Used with a vertical frame booster (TDA8174A for a 90° chassis,
STV9306 for a 110° chassis), they allow multistandard (BGDKIMNLL’, PAL/SECAM/NTSC) sets to be de-
signed with very few external components and no manual adjustments.
