New 100BASE-T PMD Jig Prototype
At the IOL, we have been using the same style jig for our 100BASE-T PMD (Clause 25) test system for many years which allows us to interface a 100BASE-T device to our digital oscilloscope. The jig is made up of an RJ45 connector contained in a plastic sleeve, a PCB that has all the components mounted on it, and the TX and RX pairs are routed through the board to SMA connectors ......

Comments (0)MIPI Battery Interface Charges Up
Battery life is one of the most important characteristics of a mobile device. No one wants to be chained to a power outlet. But batteries charge and discharge differently based on environmental factors. To help address this issue, the MIPI Alliance has created a new single wire interface for communicating with batteries within a mobile device. In February 2012, the MIPI Alliance announced MIPI Bat ...... Read More

Comments (0)IOL Student Employees: Gaining Experience, Making Connections and Building a Future
It’s common for a college student to have some sort of job. But how many of them actually enjoy what they do? How many have positions that relate to what they want to do in the future? I am one of the lucky few that can say I look forward to coming to work each day, to a job that is preparing me for the future. The InterOperability Lab (IOL) is a place where students, like myself, can explo ...... Read More
Comments (0)High Performance Computing at the IOL
High Performance Computing (HPC) is no longer exclusively the realm of uber-expensive “Super-Computers” with proprietary transport technologies and software. High Performance, as implied, requires significant compute power and high speed memory, storage, and network interconnect. To achieve High Performance, each processor must communicate rapidly, and with little CPU/ker ...... Read More
