The minimum Tx attenuation can be configured via
adi_adrv9025_ClgcConfigSet( ) API.
1. The absolute value of the upper limit of Tx
attenuation has been reached. Eg: If the maximum
Tx attenuation limit has been configured as 10dB,
and the user requests a loop gain that causes CLGC
to increase the Tx attenuation to a value greater
than 30dB, then the CLGC limits the Tx attenuation
to 30dB in this case and returns this error status.
2.
3. The maximum Tx attenuation can be configured via
adi_adrv9010_ClgcConfigSet( ) API.
An expected loop gain change from the user has been
detected and CLGC will re-initialize.
A Tx attenuation change from the user has been
detected and CLGC will re-initialize
The limit for the maximum no. of batches per CLGC run
has been breached and the CLGC is not able to estimate
the loop gain correctly for it to converge
CLGC algorithm has detected a PA protection assertion

CLGC ORx capture did not
complete successfully

Preliminary Technical
such that the loop gain falls within the
range acceptable to the user.
Adjust the Tx attenuation upper
•
limit to increase the range of Tx
attenuation accesible to the CLGC
algorithm
If the absolute maximum value of
•
Tx attenuation is reached, then it
is recommended to adjust the
loop gain such that the loop gain
falls within the range acceptable
to the user.
No action expected from the user
•
If the CLGC does not recover
•
from this state, please examine
the Orx qualifying threshold
No action expected from the user
•
If the CLGC does not recover
•
from this state, please examine
the Tx qualifying threshold
Increase the batch sample time.
The ORx channel has a low SNR that
could be causing this error. Examine
the ORx path.
Decrease Tx attenuation of the
•
signal to recover from a PA
protection error.
Increase the digital back off in the
•
baseband Tx signal
Recommended Recovery Actions
Verify that the ORx channel in
•
question is NOT enabled.
Verify that a valid path exists b/w the
•
Tx channel and ORx channel in
question.
