Overview
For Use in TV/VTR Applications
VIF/SIF Signal Processing IC
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.
