S tand-Alone Fixed-Frequenc y Operation
After power up the transceiver is set to fixed-frequency mode. In this mode, pins FS0/SDEN and FS1/LD
must be connected to V
EE
or V
CC
to set the desired frequency of operation. The logic levels at pins FS0/SDEN
and FS1/LD must not be changed after power up in order to remain in fixed-frequency mode. The default
settings of the control word bits in stand-alone mode are described in the frequency selection table.
