Overview
The LA75501V is an adjustment free VIF/SIF signal processing IC for PAL TV/VCR. It supports 38MHz, 38.9MHz, and 39.5MHz as the IF frequencies, as well as PAL sound multi-system (M/N,B/G, I, D/K), and contains an on-chip sound carrier trap and sound carrier BPF. To adjust the VCO circuit, AFT circuit, and sound filter, 4MHz external crystal or 4MHz external signal is needed.

Function
•VIF Block:  VIF Amplifier, PLL Detector, IF AGC, RFAGC, Equalizer, amplifier, Buzz Canceller, SIF Trap, Digital AFT, FLL, 4MHz X’tal oscillation
•1st SIF Block:  1st SIF Amplifier, 1st SIF Detector, 1st SIF AGC
•SIF Block:  Limiter Amplifier Down Converter,PLL FM Detector SIF PLL SIF VCO, SIF BPF
•Others:  IF SW (38.9MHz, 38MHz), SIF4 System SW (B/G, I, D/K, M/N), IFAGC 2nd filter
