Around the time I graduated college, starting salaries for engineering graduates were climbing rapidly. My first raise was a whopping 13 percent, so I could be making slightly more than the next year's crop of EE graduates.
Two stories jumped out at me this week. The first was the long-anticipated announcement by the Federal Aviation Administration that passengers will be able to use personal electronic devices during all phases of flight, which now notably includes take-offs and landings.
You've probably noticed that 28Gbit/s serial links are hot topics at DesignCon. The IEEE 802.3 working group specifies four lanes at 28Gbits/s in the emerging 100 Gigabit Ethernet family of standards for copper wires and backplanes.
If you characterize high-speed digital signals, you're surely familiar with the idea of separating jitter into components such as random jitter (RJ), deterministic jitter (DJ), periodic jitter (PJ), and intersymbol interference (ISI). What is not always discussed is the reference from which jitter measurements are made.
