6 / 86 page  STV224XH/228XH/223XH - GENERAL DESCRIPTION 6/86 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. 1.2 PIN DESCRIPTION Table 1.
