CLOSE TO VDD
1. Place C487 close to VDD pin.
2. All grounds connect directly to GND plane on PCB.
3. Pins 1 and 20 are no connects, leave floating.
4. To ensure proper operation and receiver performance, follow the guidelines in “AN383: Si47xx 3 mm x 3 mm QFN
Universal Layout Guide.” Silicon Laboratories will evaluate schematics and layouts for qualified customers.
5. Pin 2 connects to the FM antenna interface, and pin 4 connects to the AM antenna interface.
6. RFGND should be locally isolated from GND.
7. Place Si4704/05 as close as possible to antenna jack and keep the FMI and AMI traces as short as possible.
8. 4R29,4R30->2K; 4R33->600R; C487->22nF，C490->100nF
Y4->32.768; C491,C492->22pF .
9. ESD closed to C400 for Layout pcb when ESD capacitance >1pF .
