M52334FP 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.
M52334FP Key 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
- 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
- In case of VCC and Vreg. OUT short Supply voltage range: 4.75 to 5.25 V Remended supply voltage: 5.0 V
- Incase of Vreg. OUT open Supply voltage range: 8.5 to 12.5 V
