M52334FP
PLL-SPLIT VIF/SIF IC
1
DESCRIPTION
The M52334FP 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 and FM detector.
FEATURES
Video detection output is 2V
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, 920kHz
beat, and cross color.
Dynamic AGC realizes high speed response with only single
filter.
Video IF and sound IF signal processings 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.
P-P
. It has built-in EQ AMP.
