Fri, Jun 30, 2023

In order to prevent wireless network congestion in a vehicle and enhance audio functionalities, the u-blox JODY-W5 is an automotive-grade module with Bluetooth LE Audio. It has a compact form factor and operates in temperatures up to 105 degrees C.

It blends dual-band Wi-Fi 6 and dual-mode Bluetooth 5.3 technologies, including LE Audio, and is described as both cost-effective and compact while enabling different antenna configurations.

The u-blox JODY-W5 can be used in helmet-to-helmet communication for two-wheel vehicles, EV charging solutions such as link/device configuration and data charging via an access point, telematics control and head units such as diagnostics and software updates. It can also be used for infotainment with rear seat entertainment connectivity, smartphone tethering and hands-free calling.

The module is available in two operating temperature variants, operating at up to +85 and +105 degrees C meeting Automotive Grade 2 requirements. On request, the JODY-W5 provides an LTE-coexistence filter and antenna configurations. It is pin compatible with other u-blox JODY modules for ease of migration, design flexibility and upgradability while saving time and cost.

Enhanced security features support secure boot and over-the-air firmware updates, key management, and hardware encryption for critical protocol keys with NXP Semiconductors’ EdgeLock Secure Subsystem, built into NXP’s AW611. These features reduce implementation efforts considerably said u-blox, while helping avoid costly security incidents.

“By integrating the AW611 into the JODY-W5 module, we extend our partnership with u-blox, offering a solution that balances the trade-off between the adoption of latest technologies and product cost,” said Larry Olivas, general manager and vice president, Wireless Connectivity Solutions, NXP Semiconductors.

The JODY-W5 module covers RF design and certification requirements for end devices use and applications, which can be extended globally upon request, said Sebastian Schreiber, Product Strategy, Short Range Radio, at u-blox.

The globally certified module minimises the need for specific radio testing, explained u-blox, enabling a faster time to market. The first samples will be available by the end of the third quarter of 2023.

Ultrasonic sensor has rapid responsiveness for vehicle autonomy

Tue, Jun 27, 2023

Murata introduced an ultrasonic sensor device for deployment in automotive applications. The MA48CF15-7N exhibits high sensitivity and rapid responsiveness, said Murata. The MA48CF15-7N is housed in a hermetically-sealed package to protect against liquid ingress.

The accuracy of short / medium-range object detection mechanisms will need to increase to meet the demands of vehicle designs, said Murata. They will be needed to determine an object’s presence and gauge distances to accommodate higher levels of autonomy by emitting ultrasonic waves and detecting their reflections, explained the company.

The MA48CF15-7N is capable of covering a wide detection range, from 150mm to 5.5 metres for high obstacle detection accuracy. It generates a beam across an angle of 120 by 60 degrees. The 1100pF ±10 per cent capacitance (at 1kHz) is another important aspect, with the narrow deviation exhibited meaning that no transformer adjustment is required.

The resonant frequency is 48.2 ±1.0kHz and there is a 35 ±10 Q value for improved usability with better temperature performance. Tolerances on these two parameters are reduced by 50 per cent compared to previous Murata models, said the company, enabling much smaller variations in the detection characteristics of individual units.

Murata manufactures electronic components, modules and devices. Its complete portfolio includes ceramic capacitors, resistors / thermistors, inductors / chokes, timing devices, buzzers, sensors and EMI suppression filters. The company is also a ceramic capacitor manufacturer, specialising in Bluetooth and WiFi modules, board-mount DC/DC converters and is a manufacturer of standard and custom AC/DC power supplies.

Established in 1944, Murata is headquartered in Japan and has European offices in Finland, France, Germany, Hungary, Italy, the Netherlands, Spain, Switzerland and the UK.

RF calibration and verification testing automates V2X chipset production

Tue, Jun 13, 2023

Keysight Technologies’ PathWave Test Executive for Manufacturing Developer Version now supports automated RF calibration and verification testing for the Autotalk cellular vehicle to everything (LTE V2X) and dedicated short range communications (DSRC) chipsets. The chipsets are typically used in telematics control units which are embedded onboard systems that control wireless tracking, diagnostics and communication to and from a connected vehicle.

New vehicles are being equipped with multiple wireless systems which can present increased testing complexity and more complicated, expensive and time-consuming test and validation procedures. Telematics in particular, are required to interface with dozens of network technologies and communications protocols, said Keysight.

Off-the-shelf support for Autotalks chipsets automates complex calibration and verification testing to accelerate time to market, said the company. The software based test supports industry-leading chipsets, including 5G V2X, LTE V2X and DSRC communication chipsets. It also accelerates complex testing scenarios with automated control of Autotalks chipset and Keysight test instruments used as a standard test solution for a production line.

It also reduces deployment time and costs because the off the shelf test software does not require manufacturers to develop or maintain costly custom testing software or have deep wireless / radio frequency expertise for its development and use, explained Keysight Technologies.

The testing software runs on the Keysight E6640A wireless test set and is automated by the KS8328A PathWave Test Executive for Manufacturing Developer Version.

Amos Freund, vice president of R&D at Autotalks, said: “This collaboration with Keysight Technologies gives our mutual customers access to a turnkey calibration and verification solution, instead of going through the costly internal development process. Keysight implemented and automated Autotalks’ calibration guidelines and optimised it for performance utilising Keysight’s equipment capabilities.”

Thomas Goetzl, vice president and general manager of Keysight’s Automotive and Energy Solutions, said: “This solution . . . abstracts the complexity of RF calibration and verification of chipsets into a simple and easy-to-use test sequence”.

Keysight Technologies delivers design, emulation and test solutions to help engineers develop and deploy faster, with less risk, throughout the entire product lifecycle. It serves customers in communications, industrial automation, aerospace and defence, automotive, semiconductor, and general electronics markets.
