... TDA7479 Figure 4. RDS timing diagram 3 OUTPUT TIMING 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. 4)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 ...
