SAA6588

Product Summary

The SAA6588 is a RDS/RBDS pre-processor. The SAA6588 is a CMOS device that integrates all RDS/RBDS relevant functions in one chip. The IC contains filtering and demodulation of the RDS/RBDS signal, symbol decoding, block synchronization, error detection, error correction and additional detectors for multi-path, signal quality and audio signal pauses. The pre-processed RDS/RBDS information is available via the I2C-bus.
