Overview

The LA2232 and LA2232M are RDS demodulator ICs that provide both a 57 kHz bandpass filter as well as ARISK and DK signal recognition functions on chip. Costeffective 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.

Features
