PLL-SPLIT VIF/SIF IC  
DESCRIPTION  
PIN CONFIGURATION (TOP VIEW)  
The M52342FP 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  
Video detection output is 2VP-P. It has built-in EQ AMP.  
The package is a 24-pin flat package, suitable for space saving.  
The video detector uses PLL for full synchronous detection  
circuit. It produces excellent characteristics of DG, DP, 920kHz  
beat, and cross color.

filter.  
QIF DET IN  
Vcc  
Video IF and sound IF signal processings are separated from  
each other. VCO output is used to obtain intercarrier. This PLL-  
SPLIT method and built-in QIF AGC provide good sound  
sensitivity and reduces buzz.

As AFT output voltage uses the APC output voltage, VCO coil is  
not used.  
Outline 24P2N-A  
Audio FM demodulation uses PLL system, so it has wide  
frequency range with no external parts and no adjustment.  
APPLICATION  
TV sets, VCR tuners
