The ADRV9001 ARM proceeds through the calibrations in the required sequential order. The system's initial calibrations are performed first,
followed by receiver initial calibrations, and then transmitter initial calibrations.

The calibration order is mostly determined by the algorithm dependency. It is important to wait for these calibrations to complete successfully
before continuing with the other steps of initialization for the device.
Note:
Table 62
provides a full list of initialization calibrations for the device.
System Considerations for Transmitter Initial Calibrations
In this section, high level block diagrams show the device configurations and external system requirements for some transmitter initial
calibrations. In all the diagrams, grayed-out lines and blocks are not active in the calibration. Note that as the ADRV9001 ARM performs each
of the calibrations, it configures the ADRV9001 device per the following diagrams, with respect to enabling/disabling paths, and so on. No user
input is required in this regard. However, it is important that external system conditions are met, such as having the power amplifier off for all
calibrations except for some initialization calibrations utilizing ELB2.

Description
Performs VCO frequency calibration, VCO real-time temperature/aging
calibration, and charge pump calibration to make RF PLL ready for
operation. It is only used for very fast frequency hopping mode. This is
not enabled currently.
