AD9375_ORX-AGC

Product Number: AD9375

HI!

I went through AD9375 UG-992 and have the below query,

In page 175, "The device supports manual gain control (MGC) for all channels in the ORx path"

and in page 127, " The observation receivers (ORx1 and ORx2) feature manual gain control (MGC) only"

The above two statements clearly states AGC is not possible with Observation receiver, But in source code examples mentioned in page 62, the following ORX AGC function calls are shown,

1)static mykonosPeakDetAgcCfg_t obsRxPeakAgc =

2)static mykonosPowerMeasAgcCfg_t obsRxPwrAgc =

3)static mykonosAgcCfg_t obsRxAgcConfig =

So, kindly specify whether AGC is supported by ORX path of AD9375?, if not what is the purpose of the above function calls?

Thanks in-advance,

Deva

ORx path is intended for using as feedback path for DPD and hence AGC is not supported for ORX path.

Hi Srimoyi,

The Functions mentioned below are similar to RXAGC function calls,

1)static mykonosPeakDetAgcCfg_t obsRxPeakAgc =

2)static mykonosPowerMeasAgcCfg_t obsRxPwrAgc =

3)static mykonosAgcCfg_t obsRxAgcConfig =

Query:

1)then is it possible to use them to perform AGC in ORX path Also??

2)if not,what do these functions stand for and how do they differ from RXAGC function calls ?

Thanks,

Deva

The statement in UG is correct. ORX supports only MGC mode.

The API implementation is there, but the ORX AGC mode is not supported or tested by ADI.
