Configuration Overview

CC1021 can be configured to achieve the optimum performance for different applications. Through the

programmable configuration registers the following key parameters can be programmed:

•

Receive / transmit mode

•

RF output power

•

Frequency synthesizer key parameters:

–

RF output frequency

–

FSK frequency separation

–

Crystal oscillator reference frequency

•

Power-down / power-up mode

•

Crystal oscillator power up or power down

•

Data rate and data format (NRZ, Manchester coded or UART interface)

•

Synthesizer lock indicator mode

•

Digital RSSI and carrier sense

•

FSK / GFSK / OOK modulation

Configuration Software

TI provides users of CC1021 with a software program, SmartRF Studio (Windows interface) that

generates all necessary CC1021 configuration data based on the user's selections of various parameters.

These hexadecimal numbers will then be the necessary input to the microcontroller for the configuration of

CC1021. In addition, the program will provide the user with the component values needed for the

input/output matching circuit, the PLL loop filter and the LC filter.

Figure 5-2 shows the user interface of the CC1021 configuration software.
