5.5 ShockBurstTM

The ShockBurstTM technology uses on-chip FIFO to clock in data at a low data rate and transmit at

a very high rate thus enabling extremely power reduction.

When operation t he TRW-24G in S hockBurstTM ,you gain access to the high data rates(1

Mbps)offered by the 2.4GHz band without the need of a costly, high-speed micro controller (MCU)

for data processing.

By putting all high speed signal processing related to RF protocol on -chip, the TRW-24G offers the

following benefits:

1. Highly reduced current consumption.

2. Lower system cost (facilitates use of less expensive micro controller).

3. Greatly reduced risk of ‘on-air’ collisions due to short transmission time.

The TRW-24G can be programmed using a simple 3-wire interface where the data rate is decided

by the speed of the micro controller.

By allowing the digital part of the application to run at low speed while maximizing the data rate on

the RF link, the nRF ShockBurstTM mode reduces the average current consumption in applications

considerably.

5.5.1 ShockBurstTM principle

When the TRW-24G is configured in ShockBurstTM , TX or RX operation is conducted in the

following way (10 kbps for the example only).
