Hi Vereese, I didn’t expect that link to point to the UArizona work on interleaving, but it does, and your question gets at what we had to work out, so I will comment a little. For Arash’s thesis work (he’s Dr. Roshanineshat now), we did interleave pairs of ADCs on the ZCU111. This required enabling the external clocking and building a board to send separate clocks to the four tiles. There is no way to interleave a pair of ADCs on the same tile, but by shifting the clock phase between two tiles you can interleave ADCs in pairs between tiles. Arash can make his thesis available aroshanines...@arizona.edu<mailto:aroshanines...@arizona.edu> and David Forbes designed the board dfor...@arizona.edu<mailto:dfor...@arizona.edu> and both are on this list. Someday very soon we will feel that our interleaving board design is tested enough and find a way to make the design available through CASPER.

So one can safely interleave 2 ADCs (both located within 1 tile) upto 8 GSPS for 4 separate inputs. Have a good one.

The quoted 4G is per ADC, not per tile, so the ZCU111 really does have 8x4GSPS samplers. The total sampling rate is indeed 32 GSPS (but this doesn't mean that you can trivially interleave all 8 channels to achieve a single super-high sample rate) Cheers Jack On Thu, 9 Jan 2025, 12:22 Vereese Van Tonder, <vere...@sarao.ac.za<mailto:vere...@sarao.ac.za>> wrote: Hi ZCU111 users, I'm looking at: https://docs.amd.com/r/en-US/ug1271-zcu111-eval-bd/SI5382A-SFP28-Clock-Recovery<https://docs.amd.com/r/en-US/ug1271-zcu111-eval-bd/SI5382A-SFP28-Clock-Recovery> which states: "The ZU28DRF-FFVG1517 contains eight multi-gigasample (4 GSPS), 12-bit RF analog-to-digital converter (RF-ADC) channels across four banks" >From this I understand that a ZCU111 board can provide upto 32 GSPS - is this >correct? Or does a tile (which contains 2 ADCs) provide 4GSPS in total, i.e. >each is clocking at only 2GSPS and therefore the board can provide 16 GSPS in >total? Thanks in advance and happy 2025.
