PLL-SPLIT VIF/SIF IC  
DESCRIPTION  
PIN CONFIGURATION (TOP VIEW)  
The M52760SP 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 and EQ AMP.

Video detection output is 2VP-P. It has built-in EQ AMP.  
The package is a 20-pin shrink-DIP, 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.

Video IF and sound IF signal processings are separated from  
each other. VCO output is used to obtain intercarrier.  
This PLL-SPLIT method provide good sound sensitivity and  
reduces buzz.

Outline 20P4B  
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.  
QIF AMP has a fixed gain, and good characteristic for NICAM.  
APPLICATION  
TV sets, VCR tuners  
RECOMMENDED OPERATING CONDITION  
In case of Vcc and Vreg. out short
