2. Typical Application Schematic
Notes:
12
1. Place C1 close to V
2. All grounds connect directly to GND plane on PCB.
3. Pins 1 and 20 are no connects, leave floating.
4. Pins 4, 15, and 16 are unused; recommend connecting to ground.
5. To ensure proper operation and receiver performance, follow the guidelines in “AN383: Si47xx Antenna, Schematic,
6. Pin 2 connects to the WB antenna interface.
7. Place Si4707 as close as possible to antenna jack and keep the FMI trace as short as possible.
