M52761SP - PLL-SPLIT VIF/SIF IC

General Description

The M52761 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.

Key Features

  • RF AGC OUT VIF IN VIF IN GND QIF DET IN IF AGC FILTER NFB M52761SP/FP.
  • Video detection output is 2VP-P. It has built-in EQ AMP. 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 double filter. Video IF and sound IF signal processings are separated from each other. VCO output is used to obtain intercarrier. This PL.
