RDS System Chipsets

For Automotive AV Equipment

Supports both the European Broadcasting Union's RDS (Radio Data System) and the US NRSC (National Radio System Committee) RBDS (Radio Broadcast Data System) standards. Performs efficient error correction using a soft decision technique. This product also supports master operation in which data is read out in synchronization with the RDS clock output.
