M52334FP Datasheet | Mitsubishi Electric

MITSUBISHI ICs (TV) PLL-SPLIT VIF/SIF IC DESCRIPTION The M52334FP 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 and FM detector.

OUT VCO COIL VCO COIL VCC VIDEO OUT SIF GND - - - - - - - - Video detection output is 2VP-P. It has built-in EQ AMP. The package is a 20-pin flat package, suitable for space saving. The video detector uses PLL for full synchronous detection circuit. It produces excellent characteristics of DG, DP, 920k Hz beat, and cross color. Dynamic AGC realizes high speed response with only single filter. Video IF and sound IF signal processings are separated from each other. VCO output is used to obtain intercarrier. As AFT output voltage uses the APC output voltage, VCO coil is not used. Audio FM demodulation uses PLL system, so it has wide frequency range with no external parts and no adjustment. This IC corresponds to only inter of NTSC system.
