First DUT card built after the new Gen-4 motherboard, it plugs in as as DUT (device-under-test) or FuncMon and is available from XRTC partner Silicon Turnkey Solutions. The card may be populated with either the biggest monolithic device (980T) or for 200 more i/o pins (1100 total, not counting MGTs), the stacked-silicon 1140T; other footprint-compatible options are 485T or 690T devices. Industry-standard FMCs (FPGA mezzanine connectors) of the HPC (high pin count) type support a variety of custom and commercial granddaughter cards. Intended for use on the XRTC Gen4 backplane with full connectivity (among other things this will allow testing of flight designs), the on-board oscillators allow standalone use and checkout.

<hi #fff200>-[first DELIVERY, May 8, 2019]-</hi>
Update, 5-23-19: Now delivered boards with all four types of Virtex-7's!

First build successful! All features checked so far work, including MGTs (at 3.125 GHz); note: use MGT's with some extra care and thought as only one bank has D/C blocking (ie, A/C coupling) capacitors on RX pins.

Currently undergoing final review, the long awaited next-gen motherboard is expected to be formally released for manufacture soon (mid-Jan. 2018). The more we order, the cheaper the per-copy cost becomes. For ordering details, please contact Neil Sampson, , 602.770.9084 (cell) .
Volunteers needed for the Infrastructure Team which meets on Thursday mornings, 8am PST. The more eyes and brains scrutinizing the design, the more likely we get it right the first time. Next up: the KU060 DUT card. On hold: US/US+ Virtex DUT card.
