... SINGLE CHIP RDS DEMODULATOR Figure 1. Packages Table 1. Order Codes EBU (European Broadcasting Union) specifications. The device is made up of two sections: a cascaded antialiasing + switched capacitors 8 for precise RDS band selection and a demodulating section that performs the extraction od RDS data stream (RDDA) and clock (RDCL further pro- cessed by a suitable RDS decoder ...

... The RDS (1187.5Hz) output clock on RDCL line is synchronized to the incoming data. According to the internal PLL lock condition data change can result on the falling or on the rising clock edge. (see Fig. 1)Whichever clock edge is used by the decoder (rising or falling edge) the data will remain valid for 416.7 µs after the clock transi- tion. ...
