I’m using the RFSoC 4x2. I made a mistake in the clocking. I was clocking my ADC with the 409.6MHz reference clock as opposed to the 491.52MHz reference. I’m not entirely sure why it would be a problem but I’m well aware of the pitfalls that lay in incorrect clocking. It works just fine now. I hope this can be a reference to future explorers. 
Here’s an updated photo as well.
