Preliminary Rev. 0.4 29
6.8. Si47xx GUI - Radio Data Service (RDS) Window
The RDS/RBDS feature is only available in the Si4711/13 part and the Si47xx GUI allows user to evaluate the
RDS/RBDS transmission on these parts. This user guide assumes that the user is already familiar with the
RDS/RBDS standard.
User may refer to the following documents if needs to be familiar with the RDS/RBDS standard:
1. United States RBDS Standard by National Radio Systems Committee, April 9, 1998.
2. RDS Universal Encoded Communication Protocol Version 5.1 by European Broadcasting Union, August 1997.
3. Silicon Labs AN243: Using RDS/RBDS with the Si4701/03
In order for the user to transmit RDS please check the RDS On box. Failure to turn on RDS means that the RDS
data will not be transmitted. The following picture illustrated the RDS On box that should be turned on.
Figure 27. Turning on RDS in the Main GUI Window
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 play around with what kind of RDS data will be transmitted and also allows
the user to gain insight to the Si471x RDS capability.
