SYZYGY Ports

XEM7320 Pins Reference

Pins Documentation

Opal Kelly Pins is an interactive online reference for the expansion connectors on all Opal Kelly FPGA integration modules. It provides additional information on pin capabilities, pin characteristics, and PCB routing.

Pins can also generate constraint files (XDC) and help you map your HDL net names to FPGA pin locations automatically.

The Pins reference for the XEM7320 may be found at the link to the right.

Peripheral Mounting

ERRATA NOTICE

Revision 20171003 of the PCB has an incorrect mounting hole diameter for the SYZYGY ports. Please see the Product Lifecycle page for more details.

SYZYGY peripherals can be mechanically connected together using the carrier and peripheral mounting holes. Below are some suggested mounting hardware options. The Standard Hardware mounting kit is available from the accessories section of our store.
