Notes:

1.

To ensure proper operation and

receiver performance, follow the

guidelines in “AN383: Universal

Antenna Selection and Layout

Guidelines.” Silicon Laboratories will

evaluate schematics and layouts for

qualified customers.

2.

Place Si4736/37/38/39 as close as

possible to antenna jack and keep

the FMI and AMI traces as short as

possible.

Ordering Information:

See page 30.
