M52334FP 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 kHz 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 Recommended Operating Condition In case of VCC and Vreg. OUT short  Supply voltage range: 4.75 to 5.25 V  Recommended supply voltage: 5.0 V Incase of Vreg.
