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
Package Dimensions
unit: mm
3067-DIP24S
[LA2232]
Functions
• 57 kHz bandpass filter
• RDS signal demodulation
• Bit rate clock regeneration
• RDS identification output

• DK identification output
• Adjustable ARI detection sensitivity
unit: mm
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.
