DESCRIPTION
The STV223XD/223X/224X are fully bus con-
trolled ICs for TV including PIF, SIF, luma, chroma
and deflection processing. Used with a vertical
frame booster (TDA1771 or TDA8174 for 90°
chassis, STV9306 for 110° chassis), they allow
the design of multistandard (BGDKIMNLL, PAL/
SECAM/NTSC) sets with very few external com-
ponents and no manual adjustments.
