ShockBurst™

The ShockBurst™ technology available on many Nordic chips uses on-chip FIFO to clock in data at a low data rate and transmit that data at a very high rate, enabling greater power reduction. When operating in ShockBurst™ mode, the user gains access to the high data rates (1Mbps) offerred by the 2.4GHz band without the need of a costly, high-speed microcontroller (MCU) for data processing.

By putting all high speed signal processing related to RF protocol on-chip, the following benefits are achieved:

Duoceiver™ Simultaneous Two Channel Receive Mode

The Duoceiver™ technology provide 2 separate dedicated channels for RX and replaces the need for two stand alone receiver systems. This means that an RF receiver can receive data from two 1 Mbps transmitters 8 MHz apart through one antenna interface. And the output from the two data channels is fed to two separate MCU interfaces

There is one absolute requirement for using the second data channel. To be able to receive at the second data channel, the frequency channel must be 8MHz higher than the frequency of data channel 1. The chip must be programmed to receive at the frequency of data channel 1. No time multiplexing is used to fulfil this function. In direct mode, the microcontroller (MCU) must be able to handle two simultaneously incoming data packets if it is not multiplexing bewteen the two data channels. In ShockBurst™ it is possible for the microcontroller (MCU) to clock out one data channel at a time while data on the other data channel waits for MCU availability, without any lost data packets, and by doing so reduce the needed performance of the MCU.
