avoided. This improves the grounding and

ensures the shortest possible return path for

stray currents.

The external components should ideally be as

small as possible (0402 is recommended) and

surface

mount

devices

are

highly

recommended. Please note that components

smaller than those specified may have

differing characteristics.

Precaution should be used when placing the

microcontroller in order to avoid noise

interfering with the RF circuitry.

It is strongly advised that the CC1150EM

reference design ([1] and [2]) layout is followed

very closely in order to get the best

performance. Gerber files and schematics for

the reference designs are available for

download from the TI website.

Configuration Overview

CC1150 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

•

Transmit mode

•

RF channel selection

•

Data rate

•

Modulation format

•

RF output power

•

Data buffering with 64-byte transmit FIFO

•

Packet radio hardware support

•

Forward Error Correction with interleaving

•

Data Whitening

Details of each configuration register can be

found in section 25, starting on page 42.

Figure 7 shows a simplified state diagram that

explains the main

CC1150 states, together with

typical usage and current consumption. For

detailed information on controlling the

CC1150

state machine, and a complete state diagram,

see section 16, starting on page 30.
