Product Summary

The SAA6579 is a Radio Data System 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 (microcomputer). The operational functions of the device are in accordance with the“CENELEC EN 50067”.

Parametrics

SAA6579 absolute maximum ratings: (1)analog supply voltage, VDDA: 0 to 6 V; (2)digital supply voltage, VDDD: 0 to 6 V; (3)voltage on all pins; grounds excluded, Vn: -0.5 to VDDX +0.5 V; (4)storage temperature, Tstg: -40 to +150℃; (5)operating ambient temperature, Tamb: -40 to +85℃; (6)electrostatic handling for all pins except pins 9 and 10, Ves: ±300V; Ves: +1500 to -3000 V.
