Molex has released compact power over coax solution

Wed, Jan 29, 2025

Molex, has announced the availability of its new compact MMCX Power over Coax (PoC) solution, which features a patent-pending mating technique to ensure secure and stable connections while maintaining electrical ground continuity. This product innovation is ideally suited for space-constrained applications where reliable RF connections and continuous power delivery are paramount, such as automotive liquid-crystal display (LCD) mirrors, driver monitoring systems or industrial sensors.

The MMCX Power over Coax (PoC) product not only alleviates persistent reliability problems, it also is backward compatible with IEC 61169-52 MMCX jack receptacles to facilitate seamless product upgrades. This alleviates the need to redesign existing PCB receptacles, which can save significant time while reducing costs associated with product integration. Compliance with current and future standards offers customers a future-proof solution to meet evolving RF connection and power delivery requirements.

The compact product is 30% smaller than traditional MMC connectors, making it ideal for customers seeking to replace larger, heavier MCX connectors as well as more robust and reliable performance. MMCX Power over Coax is especially advantageous in applications where separate power and data connectors is either impractical or undesirable. To date, MMCX Power over Coax is being tested and deployed in a variety of agriculture, automotive and industrial automation applications.

Additionally, this future-proof solution improves performance for a vast range of miniaturised, rugged and reliable products, encompassing remote and mobile devices, unmanned aerial vehicles, portable electronics, smart-home automation systems, as well as IoT sensors and infrastructure. MMCX Power over Coax also accommodates the stringent reliability requirements for GPS antennas, intelligent transport management systems, wireless meter readers and more.

Microchip launches the next generation of its low-noise chip-scale atomic clock

Tue, Jan 28, 2025

Microchip has announced its second generation Low-Noise Chip-Scale Atomic Clock (LN-CSAC), model SA65-LN, in a lower profile height and designed to operate in a wider temperature range, enabling low phase noise and atomic clock stability in demanding conditions.

Microchip has developed its own Evacuated Miniature Crystal Oscillator (EMXO) technology and integrated it into a CSAC, enabling the model SA65-LN to offer a reduced profile height of less than ½ inch, while maintaining a power consumption of <295 mW. The new design is optimal for aerospace and defense mission-critical applications such as mobile radar, dismounted radios, dismounted IED jamming systems, autonomous sensor networks and unmanned vehicles due to its compact size, low power consumption and high precision. Operating within a wider temperature range of -40°C to +80°C, the new LN-CSAC is designed to maintain its frequency and phase stability in extreme conditions for enhanced reliability.

The LN-CSAC combines the benefits of a crystal oscillator and an atomic clock in a single compact device. The EMXO offers low-phase noise at 10 Hz < -120 dBc/Hz and Allan Deviation (ADEV) stability <1E-11 at a 1-second averaging time. The atomic clock provides initial accuracy of ±0.5 ppb, low frequency drift performance of <0.9 ppb/mo, and maximum temperature-induced errors of < ±0.3ppb. Together, the LN-CSAC can save board space, design time and overall power consumption compared to designs that feature two oscillators.

The crystal signal purity and low-phase noise of LN-CSAC are designed to ensure high-quality signal integrity, which is essential for frequency mixing. The atomic-level accuracy allows for longer intervals between calibrations, which can help extend mission durations and potentially reduce maintenance requirements.

Upgraded sensor board from ST accelerates plug-and-play evaluation

Tue, Jan 28, 2025

ST’s latest-generation sensor evaluation board, the STEVAL-MKI109D. is now upgraded with an STM32H5 microcontroller, USB-C connector, and extra digital interfaces including I3C for flexible communication , the new board lets users quickly evaluate sensors and handle demanding projects.

Engineers unveiled the STEVAL-MKI109D during a live tech lab, showing how to simply plug in a sensor module, connect a PC, and start analysing data in ST MEMS Studio. Using this all-in-one graphical environment, developers can visualise the sensor output, quickly fine-tune settings, configure features, and exercise the AI capabilities of ST sensors with a machine-learning core (MLC) and intelligent sensor processing unit (ISPU) inside. The tool provides advanced functions including power monitoring and supply voltage management that help optimise energy consumption and debugging.

ST’s MEMS portfolio contains inertial sensors, pressure sensors, biosensors, and digital and analog microphones offering many choices of speed, accuracy, full-scale range, and package style in industrial, consumer, and automotive grades. Extremely compact and robust, they are suited to diverse applications including consumer products, smartphones, wearables, smart-home devices, industrial sensing, safety equipment, healthcare, environmental monitoring, and many more. Automotive-grade devices target applications including navigation support, advanced driver assistance, and automated driving.

An evaluation module is available for each sensor type, mounted on a convenient DIL24 card with headers, ready to connect to the STEVAL-MKI109D board. Additional plug-and-play accessories are available, including biosensor electrodes and remote-sensing extension cables to quickly evaluate sensors when building proof-of-concept models and developing prototypes.

The STM32H5 MCU at the heart of the new board has the latest high-performing and efficient Arm® Cortex®-M33 core with extensive peripherals that enable faster, more convenient development. Customers’ sensor projects can target any of the over 1400 microcontrollers and microprocessors in the STM32 family. The MLC, finite-state machine (FSM), and ISPU embedded in select MEMS devices help optimise application performance and power consumption for superior functionality, responsiveness, and battery runtime.
