M52761FP

PLL-SPLIT VIF/SIF IC; ? Video detection output is 2VP-P. It has built-in EQ AMP.\n? The video detector uses PLL for full synchronous detection circuit. It produces excellent characteristics of DG, DP, 920kHz beat, and cross color.\n? Dynamic AGC realizes high speed response with double filter.\n? Video IF and sound IF signal processings are separated from each other.\n?? VCO output is used to obtain intercarrier.\n?? This PLL-SPLIT method and built-in QIF AGC provide good sound sensitivity and reduces buzz.\n? As AFT output voltage uses the APC output voltage, VCO coil is not used.\n? Audio FM demodulation uses PLL system, so it has wide frequency range with no external parts and no adjustment.\n? This IC corresponds to only NTSC system.APPLICATION\n? TV sets, VCR tuners?;

DESCRIPTION\nThe M52761 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, QIF AGC and EQ AMP.FEATURES\n?
