Bits Corresponding Enum Calibration Description
the same for all dynamic datapath profiles, gain indices
and frequency regions and so on The calibration need
only be performed on a single channel.
D7 ADI_ADRV9001_INIT_CAL_TX_DAC Tx DAC Initial
Calibration
This is used to calibrate the DAC for the required profile
bandwidth.
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
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 Rx RFDC 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_RX_DMR_PATH_DELAY Rx DMR Path
Delay Initial
Calibration
This is used to measure the delay from internal FIFO to
sync detection time needed in DMR and P25 monitor
mode.
D22 ADI_ADRV9001_INIT_CAL_PLL PLL Initial
Calibration
This is used to perform VCO frequency calibration, VCO
real-time temperature/aging calibration and charge
