VIF/SIF Signal Processing IC
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.
