LO Change Procedure
To set the LO frequency to a particular channel, user needs to
1. Verify the internal ARM microprocessor has been initialized
2. If device is on RF_ENABLED state, user needs to set it to PRIMED state by calling adi_adrv9001_EnableRf()
3. Once device is in PRIMED state, Set the LO frequency by calling adi_adrv9001_Radio_Carrier_Configure(). User can specify a
Normal or a Fast calibration by setting pllCalibration argument.
4. Lastly set turn the device to RF_ENABLED state by calling adi_adrv9001_EnableRf()
User does not have specific control over CLK_PLL. Configuration of CLK_PLL is done by calling initAnalog function. initAnalog
function programs the CLK_PLL based on information set in the device profile. This is done at initialization time
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 needs to be
called at PRIMED state, similar to setting the LO frequency.
