Notes:

1. To ensure proper operation and FM

receiver performance, follow the

guidelines in “AN350: Si4708/09

Antenna, Schematic, Layout, and

Design Guidelines" and “AN383:

Si47xx Antenna Selection and

Universal Layout Guidelines.” Silicon

Laboratories will evaluate schematics

and layouts for qualified customers.

2. Place Si4708/09 as close as possible

to antenna jack and keep the FMI

trace as short as possible.
