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.

8 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 be
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.
