Image compression technology to save power in the blink of an eye
Feb
Claimed to halve memory bandwidth and footprint, the IP block targets SoC development for consumer applications to meet the needs of the higher resolution demanded by 4K and 8K displays, as well as the battery life for consumer products. Nigel Leeder, executive vice president, PowerVR, Imagination, said: “By introducing visually lossless compression into our G…
Recom free ac-dc PSU book is good
Feb
Written by the firm’s technical director Steve Roberts, it is called ‘AC/DC Book of Knowledge’.
Electronics Weekly spent a while looking through it, and gives it a thumbs up.…
TDK uses GaN PFC to shrink 500W ac-dc power brick
Feb
Within the TDK-Lambda-branded PFH500F‑28, a pair of GaN transistors have been used in a ‘bridge-less’ front-end power factor correction stage, raising efficiency in the PFC stage to 98% and peak efficiency of the over-all supply to 92% peak.
According to marketing director Martin Southam, this is the first time the firm has used GaN components in an ac-dc P…
Tiny SiTime silicon MEMS resonator hits 5ppb accuracy for 5G infrastructure
Feb
The devices are based on 100ppb parts released two years ago and, despite now including an oven, measure 7 x 9 x 6.5mm.
The firm is aiming frequency provision in 5G infrastructure, where many mini-basestations will be spread across the landscape, in less-protected locations compared with 3G or 4G basestions – on lamp posts, for example, which will be exposed to…
Neat packaging for RS232 to IO-Link converter for industrial networks
Feb
“The converter lets you connect devices like barcode scanners, printers or RS232 controllers directly to an IO-Link terminal,” said the firm, claiming: “The expensive alternative using additional special components such as RS232 cards for integration into the respective controller is now superfluous.”
Weighing 100g, the unit is 118mm long and 18mm in diam…
Hall chip can run without a magnetic ring
Feb
MLX91217 is for a conventional Hall set-up – it comes in a slim pin-thru package for integration into conventional Hall-effect measuring rings (see diagram) . Various lead shapes make it compatible with different mounting styles including surface-mount.
MLX91216 is the unusual one, employing Melexis’ proprietary ‘integrated magneto concentrator’ (IMC) …

TI adds gigabit time-sensitive networking to industrial MCUs
Feb
Called Sitara AM6x, the industrial-grade family has quad and dual Arm Cortex-A53 core variants aimed at industry 4.0 factory automation, motor drives and grid infrastructure. Gbit TSN, EtherCAT, Ethernet/IP and PROFINET are supported by a specific subsystem called PRU-ICSS-Gb. Different capability types are pin-compatible.
“AM6x processors are built for the con…
Neural network IP aimed at SoCs processing complex speech
Feb
Resources are sufficient for far-field voice recognition, where the user is metres away from the microphone. Voice-controlled digital home assistants and automotive infotainment are intended applications.
Why process speech on the local PCB?…
Self-clinching nuts and studs for automotive thin high-strength steel
Feb
Called SH self-clincing nuts and HFLH self-clinching studs are manufactured from hardened alloy.
“Due to a lightweight design and reduced need for loose hardware such as washers, these fasteners can contribute to overall weight reductions in vehicle assemblies,” claimed the firm. “Lower installed cost can be gained from the elimination of embossing operatio…
Surrey firm uses Honeywell sensors for Formula 1 and UAVs
Feb
“We needed small and accurate board mount pressure sensors. Competitor products we examined couldn’t come close,” said Dr David Birch, research director at SSL, which is a joint venture between the University of Surrey and a unnamed private company.
The sensors, for example, are used in SSL’s Digital Seven-Hole Probe, that uses pressure as a proxy to meas…
Smart air con could stabilise power grid
Feb
The lab has devised a method to control the heating and cooling systems of a large network of buildings for power grid stability, “which could allow utilities to harness the demand from a city’s worth of buildings to help balance the power grid”, said the Lab.
“We developed control schemes that don’t require a large number of calculations and can be imp…
