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
