[ADRV9009] ORx_SEL1 and ORx_SEL0 usage?

Hello,

I have some questions regarding the usage of ORXx_SEL1 and ORXx_SEL0.

As I understand, ORXx_SEL1 and ORXx_SEL0  have two purposes:

- To inform ARM core of ADRV9009 about input of ORX from which TXx.

- To drive the feedback data path by controlling external switches

Is that correct?

---------

Let's say:

If I just need 200 MHz ORX bandwidth, that means I can use both ORX1 and ORX2 during operation (each port is enable at a time). (page 181 - UG1295)

In the case of hard-wiring ORX1 to TX1 and ORX2 to TX2, ORXx_SEL1 and ORXx_SEL0 just have only one purpose:

"To inform ARM core of ADRV9009 about input of ORX from which TXx".

Is that correct?

Thanks in advance.
