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 […]
Digital signal controller incorporates two cores in a single chip
The dsPIC33CH has one core that is designed to function as a master while the other is designed as a slave. The slave core is useful for executing dedicated, time-critical control code while the master core is busy running the user interface, system monitoring and communications functions, customized for the end application. The dsPIC33CH is […]
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 […]
RF Transceiver speeds development of 2G-5G base stations, phased-array radar
Billed as the industry’s widest bandwidth RF transceiver, the ADRV9009 RF transceiver is a single-chip time-domain duplex (TDD) IC delivering twice the bandwidth (200 MHz) of previous-generation devices and replaces as many as 20 components, cutting power in half and package size by 60%. The ADRV9009 meets the rigorous antenna density and expanded network capacity […]
Connected and autonomous vehicle technology get center stage at TU-Automotive Detroit 2018
Billed as the world’s largest automotive technology expo, TU-Automotive Detroit kicked off this week in Novi, Mich. with over 150 booths and conference tracks on ADAS and autonomous vehicles, smart cities and urban mobility, connected services, and more. Automotive cybersecurity and E-mobility were among the themes we saw. Here are some of the more interesting […]
BLE SoCs get Bluetooth mesh support
Bluetooth Special Interest Group (SIG)-compliant mesh support has been extended to the widely used SmartBond Bluetooth low energy System-on-Chip (SoC) family of devices from Dialog Semiconductor plc. Dialog is rolling out mesh support for the latest SmartBond products, starting with the DA14682 and DA14683, and then closely followed by the DA14586 and the DA14585, including […]
Bluetooth Low Energy processors foster innovations in healthcare
Applications for fitness tracking and remote health monitoring have grown to such an extent that chip makers have developed SoCs optimized for counting heartbeats and calculating glucose levels. Steven Dean, ON Semiconductor Smart wearables for mobile health (mHealth) applications are an exciting area. They can monitor vital signs and drug delivery and then send data […]
Software-defined radio powers the IoT
ADCs with SDR help reduce design efforts and let designers focus on implementing more fashionable features. Ryan Liu | Microchip Technology Inc. Software-defined radio (SDR) technology finds its way into everything from multi-carrier multi-standby smartphones to innovative multi-mode mobile internet electronics. When enabled by SDR, a configurable transceiver works flexibly with software-defined carrier frequencies, easing […]
Review: Optimizing IoT battery life with the Otii
A handy gadget for analyzing current consumption helps shed light on how internet-of-things appliances can be optimized for energy efficiency. The Otii, from the Qiotech group in Sony Mobile Communications, is one of those ideas that seems obvious only after you’ve seen it. It targets developers who must minimize the current drain from batteries, a […]
New Raspberry Pi 3 Model B+ called fastest yet
Newark element14 has released the Raspberry Pi 3 Model B+, which it calls the fastest and most powerful version yet, perfecting the already outstandingly successful Raspberry Pi 3 Model B. Built on a new quad-core Broadcom BCM2837 64-bit application processor running at 1.4 GHz, the Raspberry Pi B Model B+ is over 15% faster than […]
