LA75503V
Monolithic Linear IC
VIF/SIF Signal Processing IC
for PAL TV/VCR Adjustment Free
Overview
http://onsemi.com
The LA75503V 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.
Features
•
Internal VCO adjustment free circuit eliminating need for VCO coil adjustments.
•
Internal sound carrier BPF and sound carrier trap enable easy configuration of PAL sound multi-system at low cost.
•
Considerably reduces the number of required peripheral parts.
•
Use of digital AFT eliminates problem of AFT tolerance.
•
Package: SSOP30 (275 mil)
