Low capacitance ESD protection diodes minimise impact on signal integrity

Nexperia has expanded its portfolio of low capacitance ESD protection diodes for high speed data lines. All variants are in leadless packages to improve electrical performance and signal integrity while enabling miniaturisation in automotive designs. 

The PESD18VF1BLS-Q, PESD24VF1BLS-Q, PESD30VF1BLS-Q and PESD32VF1BLS-Q are supplied in DFN1006BD-2 packages for optical inspection in automotive production lines using side wettable flanks and the PESD18VF1BBL-Q, PESD24VF1BBL-Q and PESD30VF1BBL-Q are available in the compact DFN1006-2 package.

Target applications are in interfaces such as USB, HDMI, high-speed video links and Ethernet in automotive infotainment applications. Adding additional components to a high-speed data line can deteriorate the signal integrity of the transferred data. Therefore, choosing the right components that protect the system but do not hamper the signal transmission is vital to modern high-speed automotive systems, explained Nexperia. The signal integrity performance of the diodes is enabled by the low device capacitance (as low as a typical 0.28 pF) combined with the higher standoff voltage of 18 to 32V for placement closer to the connector. For maximum design flexibility, these diodes are offered both with and without side wettable flanks, with the side wettable flanks enabling automated optical inspection (AOI). 

These AEC-Q101 automotive-qualified devices exhibit extremely deep snapback behaviour combined with a low dynamic resistance of 0.8 Ohm for improved system-level robustness and clamping performance in high-speed data interfaces.

Headquartered in the Netherlands, Nexperia is a global semiconductor company with employees across Europe, Asia, and the United States. It says it develops and produces essential semiconductors which enable the basic functionality of virtually every electronic design in the world from automotive and industrial to mobile and consumer applications. 

The company has an extensive IP portfolio and certification to IATF 16949, ISO 9001, ISO 14001 and ISO 45001 standards.

Smart sensor measures power consumption in industrial plants

The ESS 076 is a smart sensor from Stego Elektrotechnik measures power consumption to track efficiency and spending in industrial plants.

As an IO-Link sensor, the ESS 076 enables the rapid adjustment of parameters and the transmission of real time data. With its additional 4.0 to 20mA interface, the ESS 076 can be integrated easily into current projects, said Stego.

Monitoring electricity consumption helps identify inefficient operating conditions and / or energy wastage. The ESS 076 provides accurate measurement of power consumption, enabling plant operators to take action to improve energy efficiency and reduce costs. The sensor, using contactless technology, measures AC currents up to 100A on cables up to 11.4mm in diameter to detect power consumption.

The sensor directly outputs energy consumption digitally via parameterisation of the mains voltage. Continuous current measurements allow for finer process control and optimization of plant operations. With the ESS 076, manufacturers monitor power consumption in real time and use the data to adjust processes to optimise plant performance and output. Mounting options enable the sensor to also be easily retrofitted.
The ESS 076 provides precise data that helps to avoid unnecessary expenditure. The high precision measurement technology enables the ESS 076 to monitor in real time and provides an analysis of the power consumption of facilities to reduce operating costs sustainably. The collected electricity data from the ESS 076 can be used for decision making and long term planning to support investments in energy efficiency projects or capacity expansions.

Contactless connections simplify and streamline design, says Molex

The MX60 series of contactless connectivity solutions have been developed to ease device pairing, streamline design engineering and boost product reliability, said Molex.

These low power, high speed, solid state devices feature miniaturised mmWave RF transceivers and built-in antennas in a single package. They deliver faster, simpler, device-to-device communications without the use of physical cables or connectors, said the company. The MX60 solutions can offer seamless device pairing and increased communications reliability for video displays, sleek and light consumer electronics, industrial robotics and devices operating in harsh environments, the company continued.

The MX60 series is based on wireless chip-to-chip technology and more than 350 filed patent applications acquired in 2021 with the purchase of core technology and IP from high-speed, contactless connectivity company, Keyssa. The acquired technology operates at data rates from 1,0 to 5.4Gbits per second on the 60GHz band with no Wi‑Fi or Bluetooth interference.

The first models in the MX60 series replace traditional DisplayPort, Gigabit Ethernet and USB SuperSpeed connectors to reduce development time, cost and risk, explained Molex. An integrated retimer optimises signal integrity at higher data rates.

A space-saving, contactless solution that provides USB2 and other low-speed interfaces is currently in development.

“Every piece of real estate counts when designing smartphones, AR/VR glasses, smartwatches and other consumer devices,” said Walter Rivera, senior manager, wireless connectivity product manager for the Micro Solutions business unit at Molex. “By combining USB2 and other low-speed interfaces in one contactless solution, we will offer product developers a critical head-start as they won’t have to worry about fitting extra components into ever-shrinking form factors,” he added.

The MX60 series also improves the durability of products exposed to harsh environmental conditions, such as dust, moisture and corrosion. The series addresses a variety of applications and devices, including smartphones, AR/VR glasses, tablets, self-driving vehicles, video walls, industrial robotics, medical wearables and wireless docking stations.

The sealed, contact-free solutions provide significant benefits over physical metal-to-metal contacts which can degrade over time and impact product performance and reliability, claimed the company. The contactless connectivity solutions are less prone to risks associated with ingress and repeated motion, including high-vibration and rotational products. The ability to remove diagnostic ports on wirelessly charged devices also can reduce development and production costs while boosting overall product reliability.

Production samples are available for MX60 USB SuperSpeed products, for high vibration and harsh environments, including mobile devices and networking applications, MX60 Gigabit Ethernet, for wireless infrastructure, industrial automation, medtech and networking applications and MX60 DisplayPort main and auxiliary, the high speed replacements for conventional DisplayPort connectors.

Plans are underway to expand the MX60 series further by leveraging Molex’s mmWave antenna, high-speed signal integrity and volume manufacturing expertise.

RF module combines UWB and BLE with integrated antennas

Showcasing Insight SiP’s integration and miniaturisation expertise, the ISP3080 UWB-BLE module combines ultra wideband (UWB) technology with Bluetooth Low Energy (BLE).
The module is a fully integrated device, requiring only power to create a fully functioning UWB and BLE node with both antennas integrated into the module. It uses Qorvo’s QM31100 UWB chip and Nordic Semiconductor’s nRF52833 BLE device.
The company claimed that for UWB, it offers “massively improved” power consumption compared with previous generations, and interoperability via conformance to the FiRa standard. This allows UWB connections both to other vendors’ FiRa compatible chipsets and UWB equipped mobile phones, such as the latest generation Apple, Google and Samsung devices.
Ultra-low power can be achieved by using a combination of Bluetooth and the integrated accelerometer to switch on the UWB transceiver only when necessary, advised Insight SiP.
The module measures just 12 x 12 x 1.5mm. Applications include secure entry, real-time location systems, ticketing and barrier control and hands-free key solutions.

The device offers a wide range of peripherals for a selection of digital and analogue connections, including UWB, SPI, UART, I2C, programmable general purpose I/Os and on-board ADCs.
Nick Wood, sales and marketing director for Insight SiP commented: “With the FiRa standard gaining wide acceptance and the implementation of UWB on mobile phones, we believe ultra-wideband has truly “come of age” and will become an increasingly prevalent technology.”
Insight SiP has an R&D team based in Sophia Antipolis in the south of France. The company specialises in the miniaturisation of RF modules using system in package (SiP) technology. Its offers what is believed to be the smallest complete BLE module in the world, the world’s first antenna-in-package, the world’s first UWB/BLE and LoRa/BLE combo modules with integrated antennas, and the world’s smallest microcomputer in an SD card format.
Founded in 2005, Insight SiP has a subsidiary in the US, a sales office in Japan and a network of over 30 distributors across the globe.
