TRANCEIVER SUBSYSTEM (nRF905)
9.1
RF Modes of Operation
The Transceiver has two active (RX/TX) modes and one power-saving mode when the
microcontroller is running.
9.1.1
Active Modes
ShockBurst RX
ShockBurst TX
9.1.2
Power Saving Mode
Standby and SPI - programming
The transceiver mode is decided by the settings of TRX_CE, TX_EN

nRF ShockBurst Mode
The nRF9E5 uses the Nordic Semiconductor ShockBurst feature. ShockBurst
TM
makes it possible to use the high data rate offered by the nRF905. By embedding all
high speed signal processing related to RF protocol in the transceiver, the nRF905 offers
the micro controller a simple SPI interface. Data rate is decided by the interface-speed
the micro controller itself sets up. By allowing the digital part of the application to run at
low speed, while maximizing the data rate on the RF link, the nRF905 ShockBurst
mode reduces the average current consumption in applications. In ShockBurst
TM
RX,
Address Match (AM) and Data Ready (DR) notifies the MCU when a valid address and
payload is received respectively. In ShockBurst
TM
TX, the nRF905 automatically
generates preamble and CRC. Data Ready (DR) notifies the MCU that the transmission
is completed. All together, this means reduced memory demand and more available
resources in the MCU, as well as reduced software development time.
