Tricks of the trade for optimizing the energy consumption of BLE chips affect memory size, clock speed, operating modes, and other factors determined during the initial design. Emmanuel Sambuis, Silicon Labs It can be challenging to optimize Bluetooth Low Energy (BLE) applications for minimal energy consumption. An understanding of BLE and the underlying system-on-chip (SoC) […]
Clock generators, buffers, and PCIe clocks/buffers AEC-Q100-qualified for auto apps
Automotive-grade timing solutions are designed to meet the demanding clocking needs of in-vehicle systems. The new AEC-Q100-qualified timing devices include Si5332 any-frequency programmable clock generators, Si5225x PCIe Gen1/2/3/4/5 clocks, Si5325x PCIe buffers and Si5335x fanout clock buffers. These timing devices help automotive OEMs and Tier-1 suppliers simplify clock tree design, reduce system points of failure, […]
Hybrid software-defined radio tuners support DRM standard
Silicon Labs has introduced new hybrid software-defined radio (SDR) tuners, expanding its portfolio to meet the growing need of automotive radio manufacturers to support all global digital radio standards with a common platform. The new Si479x7 devices are Silicon Labs’ first automotive radio tuners supporting the Digital Radio Mondiale (DRM) standard. The Si479x7 tuners are an extension […]
Less bullet-proof than you think: Gauging security hazards on the IoT
Engineers developing products for the IoT need to plan security measures that grow more sophisticated over time to thwart attackers who get better at wreaking havoc. Lars Lydersen, Silicon Labs Skepticism about the Internet of Things (IoT) security seems to be high. Ironically, for many industries, the key to not being hacked is simply do […]
IoT interoperability specification fast tracks Thread product development
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 […]
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 […]
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 communications
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 […]
Teardown: Inside the Neurometrix Quell TENS device
A TENS device for transcutaneous electrical nerve stimulation wraps around the upper calf much like a wristwatch wraps around the wrist. Here are some of its operational secrets. A medical device called a Quell performs what’s called transcutaneous electrical nerve stimulation on the lower leg. This technique is said to relieve diabetic pain. None of […]
Mesh networking software now built into BLE radios
Wirepas and Silicon Labs today announced they have joined forces to deliver a combined hardware and software solution that unleashes the potential of multiprotocol connectivity for mesh networks. Building on their growing relationship and success in the smart metering market, Wirepas and Silicon Labs have collaborated to create an industry first: a truly concurrent multiprotocol switching solution with one ERF32 […]
