The XRM2-OPT is an XRM2 I/O Module which provides a variety of multi-gigabit communications options.

Designed for the Alpha Data PMC/XMC family of products, the XRM2-OPT provides external connectivity for the Multi-Gigabit Tranceivers (MGTs) on the FPGA board. The XRM2-OPT allows easy external connectivity by means of simple, point-to-point connection schemes implemented using off-the-shelf optical fibre. The XRM2-OPT includes a low-jitter oscillator to support high-bit rate applications.
