Overview
The LA2230 and LA2230M are RDS demodulator ICs with an on-chip 57kHz bandpass filter and ARI-SK and DK signal identifiers. A high-performance, cost-effective RDS decoder system with group/block synchronization and error detection/correction can be built using an LC7070 series device with the LA2230 or LA2230M. LA2230 and LA2230M feature adjustable ARI detection sensitivity for improved interference rejection and a highspeed charging circuit for rapid power-on start-up. Including the 57kHz bandpass filter on-chip results in lower-cost designs that use less PCB area.
