DESCRIPTION
The STV2118B is a fully bus controlled IC for TV
luma, chroma and deflection processing.
Used with STV8224 (PIF/SIF/switches), TDA1771
or TDA8174 (frame booster), STV2180(delay line),
it allows t o des ig n a PAL/ SECAM/ NT SC
(BGDKILMN) set with very few external compo-
nents and no adjustment.
