Dpd Status - Analog Devices ADRV9029 User Manual

NOTE: Please ensure that the GPIO assigned for controlling DPD actuator bypass is driven to a low state during initialization to
prevent interference with initial calibrations.

DPD STATUS

The user can obtain the status of the DPD tracking calibration during runtime through the API command
adi_adrv9025_DpdStatusGet() which updates a data structure of type adi_adrv9025_DpdStatus_t supplied by the user. The
DPD status data structure returns the following information captured in Table 13.

Description
DPD error status. Please refer to the file
adi_adrv9025_dfe_types.h for a full list of DPD
error codes returned by the DPD status. If the
DPD is functioning correctly, this parameter
should return ADI_ADRV9025_DPD_NO_ERROR.
Percentage of DPD update completed.
No. of DPD updates scheduled
No. of successful DPD updates
DPD and CLGC tracking calibrations are
synchronized through a semaphore mechanism.
This member returns SYNC_OK if both DPD and
CLGC are synchronized. If CLGC is not enabled,
then this field can be ignored.
