2.2. SSOP Typical Application Schematic
Notes:
20
1. Place C1 close to VA and C4 close to VD pin.
2. All grounds connect directly to GND plane on PCB.
3. Pins 6 and 7 are no connects, leave floating.
4. Pins 10 and 11 are unused. Tie these pins to GND.
5. To ensure proper operation and receiver performance, follow the guidelines in “AN383: Si47xx Antenna, Schematic,
6. Pin 8 connects to the FM antenna interface, and pin 12 connects to the AM antenna interface.
7. Place Si473x as close as possible to antenna and keep the FMI and AMI traces as short as possible.
Layout, and Design Guidelines.” Silicon Laboratories will evaluate schematics and layouts for qualified customers.
