Tx Rx Signal chain control

Question asked by Abhisheknaik on Jan 1, 2017

Hi,

             In Ad9371.... There are four pins TXx_ENABLE and RXx_ENABLE to control Tx and Rx signal chains... Master( ZYNQ in my case ) has to pull appropriate pins high to switch between Rx and Tx paths... Am I right???

Or does Ad9371 has intelligence to switch between the paths (Tx and Rx) depending upon the data it receives from ZYNQ?

 

            When I was going through AD9371 UG doc I came across paired gpios (19 low voltage gpio).. somebody please explain me what it is?

 

           In windows TES... gpio tab i absorb that even if pin no. 16 is not used.. It is configured as input pin. Why? Is it a bug? or That pin is always input even if we do not use it.. How to make it output pin?

 

Thank you,

 Abhishek Naik..
