XADC sampling question

[salonishirodkar]

I am using the XADC on an application where I use the Vaux4 and Vaux12 pairs. My question is, if it is sampling both pairs simultaneously, how do I access the data? From my understanding, you give the XADC the pair address using the address_in pin and the sampled bits are retrieved on the data_out line (which is a single output line). Wouldn't it be necessary to have two data outputs, one for each pair? How does it work?

Thanks & regards

Hi @salonishirodkar,

Here is a forum thread the explains the xadc in more detail. Here is the 7 Series FPGAs and Zynq-7000 All Programmable SoC XADC Dual 12-Bit 1 MSPS Analog-to-Digital Converter User Guide. Here is an xadc demo with our Arty development board. 

cheers,
