AT6588

Product Summary

The AT6588 is a RDS/RBDS preprocessor integrated the Have RDS/RBDS function of CMOS device. Chip package Contain RDS/RBDS signal filtering and demodulation, signal solution Code, block synchronization, error detection and error correction, and attach added a multichannel, signal quality and mute detection function. The AT6588 provides the I2C bus interface. This piece of the device can replace now This used in car RDS system of several pieces IC and peripheral Device. Integrated the RDS signal decoding function, reduce the In the radio microprocessor requirements. Software also tend to Jane Single change.
