Note, when changing the LO, user needs to make sure all channels that utilize the LO is configured. For example, if Tx1 and Rx1 are using
LO1, and user wants to change LO1, then user needs to configure both Tx1 and Rx1 to achieve that. If all channels (Tx1 Tx2 Rx1 Rx2) are
using the same LO, and user needs to change the LO, then user needs to configure all channels (Tx1 Rx2 Rx1 Rx2) to achieve that.
Loop Filter Configuration
Currently, the loop filter is hard-coded in adrv9001_RadioCtrlInit. This function is called at initialization time. However, user does have
access to a public API, adi_adrv9001_Radio_PllLoopFilter_Set to manually change the loop filter settings. This function must be called at
CALIBRATED state, similar to setting the LO frequency.
