AIN and AMPIN Inputs of AD9434-FMC-500EBZ Board

Hi Dear Analog Devices,

 

We bought a AD9434-FMC-500EBZ board and try to collect data together with Xilinx ML605.

 

Our photon diode outputs [0v~1.8v] signal (with SMA port), while AIN only accepts [-0.75v~0.75v] signal based on testing.

We noticed that there is another SMA port named AMPIN except AIN.

 

1. So we are wondering what's the usage of AMPIN? Is it possible that we regulate our input to desired range by AMPIN?

2. If not, is there any board that could regulate our output [0~1.8v] to desired range[-.075v~0.75v]?

 

Thanks!
