Notes:  
1. To ensure proper operation and FM  
transceiver performance, follow the  
guidelines in “AN383: 3 mm x 3 mm  
QFN Universal Layout Guide.”  
Silicon Laboratories will evaluate  
schematics and layouts for qualified  
customers.  
2. Place the Si4720/21 as close as  
possible to the antenna jack, and  
keep the FMI trace as short as  
possible.
