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 / 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 shows the user interface of the

CC1021 configuration software.

Note: The CC1020/1070DK Development Kit with a fully assembled CC1020EMX Evaluation

Module together with the

CC1021 specific software should be used for evaluation of the CC1021

transceiver.
