“Dog” PLL chases its own tail 7/23/2009
Tales From The Cube: What to do when an LC oscillator insists on wild phase gyrations around a desired phase-lock point? One engineer is able to tame the beast.USB 3.0: A simple idea full of challenges 6/11/2009
Combining 5 Gbps with the convenience of USB sounds like a sure win, but many issues are hiding behind the premise.Getting to 4G through design and test 4/9/2009
4G telecommunication technology carries explicit requirements for minimum network speed. Designers must find a way to reliably and cost-effectively reach those targets.Noisy radio link puts brakes on racing-crew communication 1/22/2009
Tales From The Cube: Interference is hampering driver-to-pit-crew communication via a 460-MHz FM system. Even disconnecting the driver's mic doesn't help. So where is the noise coming from?Hardware and software approaches implement multiple radios 12/15/2008
Miniaturization and emerging flexible software architectures will enable compact, low-power wireless devices to support communications standards ranging from Bluetooth to WiMax.The Hot 100 Electronic Products of 2008 12/15/2008
EDN's editors offer up their annual list of the year's 100 most significant ICs, components, buses, boards, EDA tools, power devices, test instruments, and more.Designing protective circuitry for DSL loops: Beware of pitfalls 12/5/2008
DSL equipment requires protection from a variety of overvoltage conditions, but the need to avoid unduly degrading circuit operation complicates circuit design.3G wireless data: about to break? 11/13/2008
Although the definitions of 3 and 4G wireless data networks, services, and terminals have been moving targets, some long-promised 3G capabilities are starting to appear. Meanwhile, 4G deployments have been delayed even further.Power-over-Ethernet chips: to the spec and beyond 10/16/2008
Power over Ethernet allows a basic Category 5 or 6 cable to carry both data and power, enabling simple and inexpensive installations of equipment such as VOIP phones, cameras, and wireless-access points.DisplayPort versus HDMI: Do we really need two digital-display-interface standards? 9/18/2008
DisplayPort silicon is beginning to appear in PCs, LCD monitors, and graphics cards. But it will probably be at least five years before prices fall and volumes ramp enough to challenge HDMI in consumer electronics.ADVERTISEMENT
