Overcoming design challenges for a radiation-tolerant, radiation-hardened Fast Ethernet interface

10 Mbps Ethernet communication has been available for Space applications for several years, however this has not been the case for Fast Ethernet (i.e. 100basetx) operating at 100 Mbps. A 100basetx interface has been developed using radiation tolerant components that can be replaced with radiation hardened components. This implementation can operate at the input baud rate allowing for a wider component selection.
