Low-power clock ICs simplify timing for 10/25/100G Ethernet designs
A new family of high-performance clock generators target 10/25/100G applications. The new Si5332 clock family from Silicon Labs uses MultiSynth fractional clock synthesis technology to deliver jitter performance of 230 fsec rms. Multiple Si5332 options spanning 6, 8 and 12 clock outputs enable clock tree consolidation for demanding applications including hyperscale data center switches, servers, […]
How to accurately measure header/connector pitch
Sometimes when you’re working with a microcontroller unit evaluation board, you need to connect a ribbon cable to the board’s header. If the ribbon cable isn’t specified, how do you know what to order that will fit the header on the MCU board? The pitch of a connector refers to the distance between the pins […]

GNSS SiPs consumes 25 mW in most environments,12 mW during instantaneous tracking
u‑blox announced the latest member of its ZOE‑M8 series of ultra‑small GNSS SiPs. The ZOE‑M8B is a GNSS System‑in‑Package (SiP) available for small battery powered consumer devices such as portable and wearable devices targeting the fitness, health monitoring, and personal tracker markets. Small battery powered devices are defined by their limited size, weight and power, which dictates that […]
EEMBC benchmark verifies energy cost of integrated microcontroller peripherals
The industry-consortium setting the standard for valuable and practical embedded system benchmarks, EEMBC, announced the availability of EEMBC ULPMark™-PeripheralProfile (ULPMark™-PP), a tool to measure the energy efficiency of microcontrollers (MCUs) and their commonly-used, programmable peripherals. The ULPMark-PP reveals how efficiently each MCU vendor has designed and implemented its integrated peripherals. Simultaneously, EEMBC is publishing the first […]
Difference between fixed and floating point
Various types of processors (DSPs, MCUs, etc.) have the ability to do math using floating point numbers, but what exactly does this mean? In general, floating point math offers a wider range of numbers and more precision than fixed point math. Knowing the difference, and when to use which type of math can make a […]
