5.10. FM Transmitter Radio Data Service (RDS)
The RDS/RBDS feature is available with the Si4711/13/21. This user guide assumes that the user is already
familiar with the RDS/RBDS standard. If necessary, the user may refer to the following documents to become
familiar with the RDS/RBDS standard.
United States RBDS Standard by National Radio Systems Committee, April 9, 1998.
RDS Universal Encoded Communication Protocol Version 5.1 by European Broadcasting Union, August
1997.
Silicon Labs “AN243: Using RDS/RBDS with the Si4701/03.”
In order for the user to transmit RDS, check the RDS On box. Failure to turn on RDS means that the RDS data will
not be transmitted. The following picture illustrates the RDS On box that should be turned on.

After the RDS transmission is enabled, click on WindowRDS Transmit Data to go to the RDS Transmit Data
screen. This window allows the user to configure RDS data to be transmitted and also allows the user to gain
insight to the Si4711/13/21 RDS capability.
