INTRODUCTION
The STV223XD/224X 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 designed with very few external components and no manual adjustments.
