CLGC API SUMMARY
Table 39. CLGC API Software Overview
API Function Description
adi_adrv9025_ClgcConfigSet
Configures the CLGC measurement and Tx attenuation control parameters as
described in the previous sections. This API can also be used to turn on/off
loop gain control
adi_adrv9025_ClgcConfigGet Retrieves the CLGC configuration currently active in the ADRV9025 device
adi_adrv9025_ClgcStatusGet Retrieves the CLGC status
CLGC CONFIGURATION SUMMARY
Table 40. Summary of CLGC parameters configurable in the data structure adi_adrv9025_ClgcConfig_t
Parameter Description Range
txChannelMask
Mask consisting of 'OR'ed Tx channels for
which the CLGC config will be applied
0x00 – 0x0F. Bit0 to Bit3 represent
channels Tx1 to Tx4.
clgcEnableGainControl
This parameter enables the tracking and
adjustment of loop gain in CLGC.
If this is set to 0, the CLGC tracking cal only
measure
s the power levels and does not
execute loop gain control
0 – Disable loop gain ctrl
1 – Enable loop gain ctrl
clgcMeasurementBatchTime_us Sampling period per batch of CLGC samples 10us to 65536us
clgcExpectedLoopGain_dB
Configured by the user depending on the
optimum operating point of the PA
No limits imposed, the expected
loop gain depends on the
application.
clgcTxQualifyingThreshold_dBFS
Minimum threshold for the Tx signal required
to run CLGC tracking
The qualifying threshold must not
go below -70 dBFS for optimum
performance
clgcOrxQualifyingThreshold_dBFS
Minimum threshold for the Orx signal required
to run CLGC tracking
The qualifying threshold must not
go below -70 dBFS for optimum
performance
clgcMaxGainAdjustmentStepSize_dB
Maximum loop gain adjustment step
size(Range 0 to 6dB) for Tx Attenuation in dB.
The maximum step size that a user
can configure is 6dB
clgcMinTxAttenAdjust_dB
Minimum Tx attenuation in dB allowed to
adjust to
The minimum Tx attenuation value
that can be set on the transceiver Tx
front end is 0dB
clgcMaxTxAttenAdjust_dB
Maximum Tx attenuation in dB allowed to
adjust to
The maximum Tx attenuation value
that can be set on the transceiver Tx
front end is 41.95dB
CLGC STATUS
The CLGC status can be retrieved using the API adi_adrv9025_ClgcStatusGet(). The CLGC status is contained in the data structure
adi_adrv9025_ClgcStatus_t. Table 41 contains a summary of CLGC status parameters in the data structure
adi_adrv9025_ClgcStatus_t.
