Bits Corresponding Enum Calibration Description
D8 ADI_ADRV9001_INIT_CAL_TX_PATH_DELAY
Tx Path Delay
Initial Calibration
This is used to estimate the delay between the Tx input
and the Tx output.
D9 ADI_ADRV9001_INIT_CAL_RX_HPADC_RC
Rx HP ADC RC
Initial Calibration
This is used to determine how much the unit R and C vary
from ideal and then tune the HP ADC’s programmable Rs
and Cs to obtain their desired values. Without this
calibration, the HP ADC’s noise performance will be
negatively impacted. The HP ADC could also become
unstable. It is not used when only LP ADC is used.
D10 ADI_ADRV9001_INIT_CAL_RX_HPADC_FLASH
Rx HP ADC Flash
Offset Initial
Calibration
This is used to optimize the HP ADC output noise by
correcting comparators offsets in the backend flash. It is
not used when only LP ADC is used.
D11 ADI_ADRV9001_INIT_CAL_RX_HPADC_DAC
Rx HP ADC DAC
Initial Calibration
It corrects for element mismatch HP ADC current. It is not
used when only LP ADC is used. This is disabled by default
– uncalibrated performance sufficient.
D12 ADI_ADRV9001_INIT_CAL_RX_DCC
Rx HP ADC
Stability Initial
Calibration
This corrects the 50% duty cycle for external LO when the
divisor is 2.
D13 ADI_ADRV9001_INIT_CAL_RX_LPADC
Rx LP ADC Initial
Calibration
This is used to calibrate the LP ADC. The major purpose of
using the LP ADC instead of the HP ADC is to reduce power
consumption. It is not used when only HP ADC is used.
D14 ADI_ADRV9001_INIT_CAL_RX_TIA_CUTOFF
Rx TIA Cutoff
Initial Calibration
This is used to tune the 3dB cut-off frequency of the TIA filter.
D15 ADI_ADRV9001_INIT_CAL_RX_GROUP_DELAY
Rx TIA Fine Initial
Calibration
This is used to compensate the mismatch in 3dB cutoff
frequency between I and Q path. It helps to correct
quadrature error in analog domain, which simplifies the
correction in the digital domain.
D16 ADI_ADRV9001_INIT_CAL_RX_QEC_TCAL
Rx Tone Initial
Calibration
This performs an initial QEC calibration in wideband
systems for frequency dependent quadrature errors.
D17 ADI_ADRV9001_INIT_CAL_RX_QEC_FIC
Rx Frequency
Independent
Error Initial
Calibration
This performs an initial QEC calibration for frequency
independent errors for both narrowband and wideband
systems.
D18 ADI_ADRV9001_INIT_CAL_RX_QEC_ILB_LO_DELAY
Rx ILB LO Delay
Initial Calibration
This is used to adjust the analog delay between the
inphase and quadrature LO components at the mixer on
the internal loopback path. This is not enabled currently.
D19 ADI_ADRV9001_INIT_CAL_RX_RF_DC_OFFSET
Initial Calibration
This is used to mitigate the RFDC offset added due to LO
self-mixing.
D20 ADI_ADRV9001_INIT_CAL_RX_GAIN_PATH_DELAY
Rx Gain Path
Delay Initial
Calibration
This is used to calculate the path delay between the Rx
analog and digital attenuation blocks. This delay is then
used to offset the onset of Rx analog and digital
attenuations relative to each other to compensate for the
path delay between these blocks. It is independent of gain
index and frequency region. The calibration needs only be
performed on a single channel.
D21 ADI_ADRV9001_INIT_CAL_PLL
PLL Initial
Calibration
This is used to perform 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.
D22 ADI_ADRV9001_INIT_CAL_AUX_PLL
Calibration
This is used to perform VCO frequency calibration, VCO
real-time temperature/aging calibration and charge pump
calibration to make aux PLL ready for operation. This is
not enabled currently.
