MicroZed IOCC XADC connector

Hi all,

I have a question regarding the IOCC XADC connector.

Looking at the schematic, it seems that the voltages (A5V,A1V8) provided are not connected to the XADC of the MicroZed itself.
Why are these voltages generated on the IOCC?
Is meant to be used for attaching an addiction ADC IC to the system?
Otherwise what is the purpose of this connector?

Thank you for the support.

These voltages and the connector itself are to accommodate the Xilinx AMS101 evalucation card.

I think the original vision for XADC is that there would be multiple cards that would fit this connector, but I'm only aware of this one. The AMS101 does make use of the A5V for several things (search for XADC_VCC5V0 on the AMS101 schematic), but the A1V8 is not even connected.

Hi Bryan,

thank you for your answer.
I just wanted to ensure that those voltage are not needed beside a kind of application like the one you mentioned.

Thank you, very appreciated!
