PCB Footprint

The PCB is 80mm x 70mm with four mounting holes (M2 metric screws) spaced as shown in the figures below.  These mounting holes are electrically isolated from all signals on the XEM7350.  The two connectors (USB and DC power) overhang the PCB by approximately 1.3mm in order to accommodate mounting within an enclosure.

The XEM7350 has a single high pin count (HPC) FMC connector providing access to over 160 I/O, 8 multi-gigabit transceivers, and electrically-programmable adjustable voltage per the VITA-57 standard.

Mechanical Drawing

Heat Sink

The device has been fitted with two heat sink anchors, proximate to the FPGA for mounting a passive or active heat sink. The following heat sinks have been tested with the XEM7350.

Aavid Termalloy3358230-PAL03010-P0Custom with fan mount

The passive heat sink above is a low cost option available through Aavid Thermalloy distributors such as Arrow Electronics and Newark Electronics.

The active heat sink above was custom built based on design specifications provided by Opal Kelly to mate to the XEM7350. It includes a small fan which connects to the fan controller on-board for manual or automatic fan control. The assigned part number should allow you to order direct from Aavid, if desired. It is available for purchase directly from Opal Kelly as FANSINK-30X30.
