Product Description  2.4G RF Transceiver Module RFM75 Module for Wireless Audio 
RFM75 is a GFSK wireless rf transceiver module operating in the world wide ISM frequency band at 2400-2483.5 MHz. Burst mode transmission and up to 2Mbps air data rate make them suitable for applications requiring ultra low power consumption.
The embedded packet processing engines enable their full operation with a very simple MCU as a radio system. Auto re-transmission and auto acknowledge give reliable link without any MCU interference.
RFM75 operates in TDD mode, either as a transmitter or as a receiver.The RF channel frequency determines the center of the channel used by RFM75. The frequency is set by the RF_CH register in register bank 0 according to the following formula: F0= 2400 + RF_CH (MHz). The resolution of the RF channel frequency is 1MHz.
A transmitter and a receiver must be programmed with the same RF channel frequency to be able to communicate with each other. The output power of RFM75W is set by the RF_PWR bits in the RF_SETUP register.
Demodulation is done with embedded data slicer and bit recovery logic. The air data rate can be programmed to 250Kbps, 1Mbps or 2Mbps by RF_DR_HIGH and RF_DR_LOW register. A transmitter and a receiver must be programmed with the same setting.
