The Zigbee Alliance and Thread Group have reached a critical milestone in IoT interoperability with the completion of the Dotdot 1.0 specification and announcement of the Dotdot over Thread certification program. For the first time, developers of smart products can confidently use a mature, open, and certifiable interoperability language over a low-power IP network. This […]
Fischer Connectors’ Freedom LP360 wins LEAP connectivity award
Last night, at the LEAP Awards dinner gala in Costa Mesa, Calif., 11 winners were announced for the first annual awards competition. In the category of Connectivity, Fischer Connectors’ Freedom LP360 connector garnered the highest award. In selecting the LP360, judges noted: “A breakthrough signal and power connector with easy mating and easy cleaning that […]
Next-generation Z-Wave protocol now on wireless Gecko platform
The next-generation Z-Wave 700 protocol can now be found on the Wireless Gecko platform from Silicon Labs. The new smart home platform builds on Z-Wave’s industry-leading S2 security and interoperability by improving energy efficiency and adding higher performance, longer range RF capabilities. By leveraging the Wireless Gecko platform, Z-Wave 700 is said to enable developers […]
Blood oxygen meters, Part 1: Background and principles
It is now trivial and non-invasive to measure blood-oxygen saturation SpO2, thanks to LEDs, algorithms, and ICs for pulse oximetry — and it’s a very long way from having to draw blood and send it out for assessment. Just a few decades ago, determining the vital medical parameter known as blood oxygen level — formally […]
LEAP Awards announces finalists in connectivity category
Four finalists were announced on Friday for the inaugural LEAP Awards’ Connectivity Category, comprising a variety of interconnect, cable and harness technologies. The competition was scored by a panel of independent technical/engineering-oriented judges. Responsible for the Connectivity category were these four judges: Plamen Doynov Research Professor University of Missouri-Kansas City. Doynov became a research professor […]
Galvanic isolation for electric vehicle systems
High voltages and high currents circulating in EVs make the fundamentals of electrical isolation techniques an important topic. Ross Sabolcik, Silicon Labs AS automotive designs move toward electrification, high-wattage power electronics become critical to new electronic drivetrain and battery systems. In these applications, digital controllers safely interface with the high-voltage systems of modern electric vehicles […]
Electrical isolation technology at Silicon Labs
When you’re talking about power products and power supplies, galvanic isolation is a big deal.In that area, Silicon Labs has a wide portfolio of products that cover everything from digital isolators, which allow you to isolate a communication bus, or other digital signals up through high powered gate drivers to allow an interface to MOSFETs, […]
Advances in Power over Ethernet ICs
Power-over-Ethernet specs have changed over the years — PoE devices have gotten more powerful, and so Ethernet cables are starting to become more like a power line. Silicon Labs’ John Wilson recently did a short video with us about four new power device ICs built with higher PoE power levels in mind. John reviewed demonstrations […]
Clocks/oscillators meet stringent 56G SerDes phase-jitter requirements
Silicon Labs has expanded its timing portfolio to meet the high-performance clocking requirements of 56G PAM-4 SerDes and emerging 112G serial applications. With this portfolio expansion, Silicon Labs is the only timing supplier to offer a comprehensive selection of clock generators, jitter attenuating clocks, voltage-controlled crystal oscillators (VCXOs) and XOs for 100/200/400/600G designs that satisfy sub-100 […]
Clock generators, jitter attenuators, VCXO/XOs target latest 56G SerDes-based 100/200/400/600G communications, data center designs
The Silicon Labs Si5391 is said to be the industry’s lowest jitter, any-frequency clock generator. It can provide all clock frequencies needed in 200/400/600G designs from a single IC while delivering sub-100 fsec RMS phase jitter performance for 56G SerDes reference clocks. Featuring up to 12 differential outputs, the Si5391 clock is available in frequency […]
