Overview
The LA2232 and LA2232M are RDS demodulator ICs
that provide both a 57 kHz bandpass filter as well as ARI-
SK and DK signal recognition functions on chip. Cost-
effective RDS decoder systems can be constructed by
using an LA2232 or 2232M in conjunction with a
synchronization and error detection/correction LSI from
the LC7070 series. The LA2232 and 2232M provide
improved sensitivity LA2230 and 2230M.
