DESCRIPTION
The M52318SP and M52323SP are IF single-processing ICs for VCRs and color TVs. They enable the PLL detection system despite size as small as that of conventional equsl-synchronous VIF/SIF ICs.
The circuit includes VIF amplifier, video detector, VCO, APC, detector, AFT, SIF detector, IF/RF AGC, SIF limiter, FM detector, QIF AGC, and EQ AMP.
