ZMOD/SYZYGY PORT on USB104 A7

[krb]

On the USB104 A7, there is a ZMOD/SYZYGY PORT.  What is that connector part number?  Are the contacts 50mm pitch or 80mm pitch?  What would be a possible mate?

I see two standoffs.  What is the standoff part number?  Spacing?  Internal thread?  How tall?

Hey krb,

The connector is Samtec part number QSE-020-01-F-D-A, 0.8 mm pitch. The included standoffs are 6 mm hex, 5 mm long, M3 x 0.50 mm thread.

Digilent hasn't published mechanical dimensions for the USB104-A7, but you might find some insight about how the R&D team handled its SYZYGY connectors in Eclypse's mechanicals: https://digilent.com/reference/_media/reference/programmable-logic/eclypse-z7/eclypsez7_pcbas_a5.pdf.

Hope this helps,
