PLL-Split VIF/SIF IC REJ03F0164-0201 Rev.2.01 Jan 25, 2008 Description The M52334FP is IF signal-processing IC for VCRs and TVs. It enables 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. Features - Video detection output is 2 VP-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, 920 k Hz beat, and cross color. - Dynamic AGC realizes high-speed response with only single filter. - Video IF and sound IF signal processing 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. Application TV sets, VCR tuners Remended Operating Condition - In case of VCC and Vreg. OUT short  Supply voltage range: 4.75 to 5.25 V  Remended supply voltage: 5.0 V - Incase of Vreg.
