Preliminary RDS DEMODULATOR IC S1A0905 GENERAL DESCRIPTION THE OUTLINE OF RDS(RADIO DATA SYSTEM) 16−SOP−225 Since 1988 most European national broadcaststations transmit RDScode beside their audio signals. RDS means Radio Data System and was originally intended to give people in their cars additional information about the weather or traffic(jams). But RDS has grown out to one big channel of information. Radiostations send their name, the time (with DCF-77 accuracy), their type of music (format) and even more. The digital data of RDS are multiplexed into an FM radio wave using a sub-carrier of 57kHz. The transmission rate of RDS data is 1.1875kbit/sec. The transmission rate of RDS data is 1.1875kbit/sec, and RDS data are encoded by differential encoding method.
