API Function Description
adi_adrv9001_Channel_EnableRf() Enable or disable RF channel
adi_adrv9001_Radio_PllStatus_Get() Checks if the PLLs are locked.
adi_adrv9001_Radio_PllLoopFilter_Set() Configures the loop filter for the specified PLL.
adi_adrv9001_Radio_PllLoopFilter_Get() Gets the loop filter configuration for the specified PLL.
adi_adrv9001_Radio_Carrier_Configure() Sets the carrier configuration for the given channel.
adi_adrv9001_Radio_Carrier_Inspect() Inspects carrier configuration.
LO Change Procedure
To set the LO frequency to a particular channel, user must:
1. Verify the internal ARM microprocessor has been initialized.
2. If device is on RF_ENABLED state, user must 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 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 must be called at
PRIMED state, similar to setting the LO frequency.
