Table 15: Bill Of Materials for the application circuit
In the CC2500EM reference design shown in
Figure 4, LQG15 series inductors from Murata
have been used. 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 are available from the TI and Chipcon
websites.

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 with interleaving
• Data Whitening
• Wake-On-Radio (WOR)
Details of each configuration register can be
found in Section 31, starting on page 51.
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 35.
