4. Universal AM/FM RX/FM TX Application Schematic
Figure 12 shows an application schematic that supports the Si47xx family of 3 mm x 3 mm QFN products,
including the Si4702/3/4/5 FM receivers, Si471x FM transmitters, Si472x FM transceivers, and Si473x AM/FM
receivers.
Following the schematic and layout recommendations detailed in “AN383:
Guidelines
AM/FM RX/FM TX Application Schematic”. System components are those that are likely to be present for any tuner
or transmitter design.
