SAA6579 Overview
SAA6579 The integrated CMOS circuit SAA6579 is an RDS demodulator. It recovers the additional inaudible RDS information which is transmitted by FM radio broadcasting. The data signal RDDA and the clock signal RDCL are provided as outputs for further processing by a suitable decoder (microputer).
