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. Important Note: FM Receiver performance is subject to adherence to antenna design guidelines in “AN231:
5. Pin 2 connects to the antenna interface, refer to “AN231: Si4700/01/02/03 Headphone and Antenna Interface.”
6. Place Si4702/03-C19 as close as possible to antenna jack and keep the FMIP trace as short as possible.
7. Refer to Si4702/03 Internal Crystal Oscillator Errata.
8. Refer to "AN299: External 32.768 kHz Crystal Oscillator."
Si4700/01/02/03 Headphone and Antenna Interface.” Failure to use these guidelines will negatively affect the
performance of the Si4702/03-C19, particularly in weak signal and noisy environments. Silicon Laboratories will evaluate
schematics and layouts for qualified customers.
