SANYO -> Panasonic 

Ordering number : EN4416A

Monolithic Linear IC

LA2232, 2232M

RDS Decorder

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.

Applications

• RDS signal demodulation

• ARI signal demodulation and SK and DK recognition

3112-MFP24S

[LA2232M]

Features

• High RDS demodulation sensitivity

• Reduced costs and PCB area due to the inclusion of an

on-chip 57 kHz bandpass filter

• Supports improved interference rejection characteristics

by providing ARI detection sensitivity adjustment

• Quick operation startup due to a built-in rapid charging

circuit for use at power application.
