... DESCRIPTION The M52760SP is IF signal-processing IC for VCRs and TVs. It enable the PLL detection system despite size as small as that of conventional quasi-synchronous VIF/SIF detector, IF/RF AGC, SIF limiter, FM detector and EQ AMP. FEATURES • Video detection output has built-in EQ AMP. P-P • The package is a 20-pin shrink-DIP, suitable for space saving. ...
