Kintex-7 XADC of vp/vn measurement

Jump to solution

I am using 7 series xc7k410tffg900 fpga to do the voltage measurement of vp/vn. The ADC operate in a bipolar mode,and I want to use the ADC B to do the measure.

My question is described as following

First I hope to make sure whether xc7k410tffg900 FPGA has two XADCs or not?

If has two how to set the ip core parameters of xadc to use the ADC B and work in bipolar mode.

Every 7-Series devices has an xadc that's dual core. 

I'd suggest using the wizard this will enable the channel and allow you to put it into bipolar input mode. 

You will not however be able to dicate which ADC is used. 

This is mostly transparent to the user and only really comes into play when using simultaneous sample mode. This is where auxiliary analog inputs are paired and sampled at the same time on each adc

Thanks a lot. It’s really helpful for me to understand XADC.
