... AX5051 sends and receives data via the SPI port in frames. This standard operation mode is called Frame Mode. Pre and post ambles as well as checksums can be generated automatically. Interrupts control the data flow between a controller and the AX5051. The AX5051 behaves as a SPI slave interface. Configuration of the the SPI interface ...

... The channel filter offers bandwidths of 40 kHz up to 600 kHz. For detailed instructions how to program the digital channel filter and the demodulator see the AX5051 Programming Manual, an overview of the registers involved is given in the following table. The register setups typically must be done once at power-up of the device. Version 1.6 23 Circuit Description Datasheet AX5051 ...

... These registers control the bit rate of the transmitter. These registers control the frequency deviation of the transmitter in FSK mode. The receiver does not explicitly need to know the frequency deviation, only the channel filter bandwidth has to be set wide enough for the complete modulation to pass. Programming Manual.
