Values shown as (italic) are out-of-band frequencies.
If FCS0=1 (connected to VDD) the RSSI threshold limit is changed from –103 dBm to –97 dBm.
In standalone mode, the operation parameters related to the band, frequency selection and chip address are determined by the
table above. All other control bits (filter bandwidth, bit rate etc.) are determined by the power-on values of the different control
registers.
It is possible to use the receiver in a so-called “mixed mode”. The SPI bus architecture allows access to the bus in standalone
mode (pins 1, 2, 3) and thereby makes it possible to overwrite the default POR values of the control registers. In this way the
operating parameters of the receiver can be programmed over the interface while performing the functions of the standalone
mode when receiving the proper data sequence.
