M52334中文资料三菱电机数据手册PDF规格书

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 2VP-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, 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.

APPLICATION

TV sets, VCR tuners
