Measurements have been performed with
multi

layer inductors from other manufacturers
(e.g. Würth) and the measurement results
were the same as when using the Murata part.

Configuration Overview
CC2500
can be configured to a
chieve optimum
performance for many different applications.
Configuration is done using the SPI interface.
The following key parameters can be
programmed:

Power
-
down / power up mode

Crystal oscillator power
-
up / power
-
down

Receive / transmit mode

RF chann
el selection

Data rate

Modulation format

RX channel filter bandwidth

RF output power

Data buffering with separate 64
-
byte
receive and transmit FIFOs

Packet radio hardware support

Forward Error Correction
(FEC)
with
interleaving

