Table 15: Bill Of Materials for the Application Circuit

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.

The Gerber files for the CC2500EM reference

design ([4]) are available from the TI website.

Configuration Overview

CC2500 can be configured to achieve optimum

performance for many different applications.

Configuration is done using the SPI interface.

The

following

key

parameters

can

programmed:



Power-down / power up mode



Crystal oscillator power-up / power-down



Receive / transmit mode



RF channel 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



Data Whitening



Wake-On-Radio (WOR)

Details of each configuration register can be

found in Section 32, starting on page 57.

Figure 5 shows a simplified state diagram that

explains the main

CC2500 states, together with

typical usage and current consumption. For

detailed information on controlling the

CC2500

state machine, and a complete state diagram,

see Section 19, starting on page 39.
