Long-reach, single pair PoE drives intelligence in factory automation

Tue, Nov 22, 2022

Believed to be the world’s first single pair power over Ethernet (SPoE) power sourcing equipment (PSE) and power device (PD) solutions to help customers drive greater levels of intelligence into smart buildings, factory automation, and other applications at the edge of traditional networks.

They are designed to facilitate powered, last-mile connectivity for factory and building automation through real-time power management, telemetry, extremely low standby power consumption and ease of installation.

“The Intelligent Edge is one of the most exciting developments of the digital era as computing power is pushed to previously inaccessible applications and locations,” said Leo McHugh, vice president of industrial automation at Analog Devices.

The SPoE solutions, the LTC4296-1 and LTC9111, address the challenges of providing power and data to devices, even in remote, difficult to access endpoint locations, said Analog Devices. They are designed to help new families of endpoint applications to be seamlessly powered and accessed across the network and used to assess local factors such as asset health, environmental conditions and security metrics.

Analog Devices’ SPoE solutions reduce reliance on localised power and batteries by using a single twisted pair of Ethernet cables to provide efficient, reliable, easily installed power at reduced size and weight. When combined with ADI’s Chronous ADIN1100 and ADIN1110 10BASE-T1L, industrial Ethernet solutions, customers can reliably transfer both power and data over 1km, representing a significant increase compared with previous Ethernet standards, said Analog Devices.

The LTC4296-1 5-port SPoE PSE with Classification and LTC9111 SPoE PD with Polarity Correction products support both SPoE and power over data line (PoDL) variants of single pair powering. SPoE augments single pair Ethernet (SPE) to provide more reliable, fault-tolerant, and interoperable point-to-point power solutions, delivering up to 52W. Both products are 802.3cg-compliant and support Serial Communication Classification Protocol (SCCP).

Analog Devices operates at the centre of the modern digital economy, with a comprehensive suite of analogue and mixed signal, power management, radio frequency (RF), and digital and sensor technologies. ADI serves 125,000 customers worldwide with more than 75,000 products in the industrial, communications, automotive, and consumer markets.

Renesas unveils family of automotive radar transceivers with high accuracy and low power consumption

Fri, Nov 18, 2022

Renesas Electronics Corporation is entering the automotive radar market with the introduction of a 4×4-channel, 76-81GHz transceiver designed to meet the requirements of ADAS (advanced driver assistance systems) and Level 3 and higher autonomous driving applications.

Renesas will incorporate the new RAA270205 high-definition radar transceiver into its growing sensor fusion portfolio, which combines radar, vision systems, and other sensing modalities.

Designed in co-operation with Steradian Semiconductors Private Limited, which Renesas acquired earlier this year, the new transceiver MMIC (monolithic microwave integrated circuit) is especially suited for imaging radar, long-range forward-looking radar and 4D radar, but can also be used for corner and central-processing radar architectures, the so-called ‘satellite’ automotive radar systems, said the company. Equipped with 4Tx and 4Rx channels, the RAA270205 supports up to 16 MIMO (multiple-input and multiple-output) channels. It can be cascaded to enable higher channel count and better radar resolution.

The RAA270205 features up to 5GHz of bandwidth and a 112.5MSPS ADC (analog-to-digital converter) sampling rate that it claims is nearly three times faster than those of competing devices. Power consumption of 1.2W is 50 per cent lower than that of comparable transceivers and it delivers a noise figure of 9dB, which is 3dB less than other radar transceivers, it says. Its chirp rate of up to 300MHz/microAs improves radar resolution and object detection.

“Today’s radar transceiver MMICs must achieve higher definition to support the high-accuracy requirements of ADAS and autonomous driving safety platforms,” said Vivek Bhan, senior vice-president and deputy general manager of Renesas’ automotive solution business unit. “Working in close collaboration with Steradian, which brings deep radar design expertise, we are expanding our sensor fusion offerings with a focus on functional safety and low power consumption to help our customers lower their development costs and improve time to market.”

Renesas plans to combine the RAA270205 transceiver with other compatible devices from its portfolio to support automotive radar systems. These combinations will include the satellite radar system for AD/ADAS, which will be available in Q2/2023.

The RAA270205 will be available in 1Q/2023 in sample quantities, with commercial production planned for 2024. The transceiver is available in a small, easy-to-integrate eWLB (embedded wafer-level ball-grid array) package, measuring 7.6×5.6mm. It will be fully compliant with automotive industry requirements such as IATF 16949, AEC-Q100 Grade2 and ASIL B.

Industrial GbE transceivers optimise process automation, says Microchip

Fri, Nov 11, 2022

As developers of industrial automation systems gravitate from proprietary solutions for process synchronisation to standard-based one that offer broader compatibility and reduce design costs, Microchip has developed the LAN8840 and LAN8841 Gigabit Ethernet transceiver devices for critical process synchronisation.

The transceivers meet IEEE 1588v2 standards for Precision Timing Protocol. The LAN8840 and LAN8841 are enabled with Linux drivers and deliver flexible Ethernet speed options including 10BASE-T, 10BASE-Te, 100BASE-TX and 1000BASE-T.

They can facilitate critical packet prioritisation by providing high speed time stamping that is relayed between components to determine network latencies, accommodate for those latencies, and synchronise time amongst all connected devices.

This timing is key for process automation applications that require precise control production systems such as robotics, distributed sensors and cooling and mixing systems. The LAN8840 and LAN8841 can withstand extended industrial temperatures ranging from -40 to +105 degrees C.

To help companies achieve sustainability, the LAN8840 / LAN8841 features wake-on-LAN (WoL) and energy-detect power-down mode. The energy-efficient Ethernet (EEE) mode delivers low power idle and clock stoppage modes for optimal power performance.

The LAN8840 / LAN8841 are suitable for applications requiring accurate and precise time stamping, such as gas and chemical processing, electrical distribution, and currency trade systems which must be proven to be in sync with the National Institute of Standards and Technology (NIST) for Universal Coordinated Time (UTC) within one millisecond or finer increments.

The LAN8841 Ethernet Development System (EDS) daughter card is a modular addition to compatible Microchip host boards. When paired with the PCIe networking adapter, it enables evaluation of the LAN8841 through any host supporting the PCIe interface. Linux drivers supporting Precision Timing Protocol (PTP4L) are available for the LAN8841 on Microchip’s GitHub repository.

The LAN8840 (48 QFN) and LAN8841 (64 WQFN) are now available in high-volume production.

Microchip Technology serves more than 120,000 customers across the industrial, automotive, consumer, aerospace and defence, communications and computing markets.

The company is headquartered in Chandler, Arizona, USA.

Mercury Systems launches DDR4 memory for edge processing in space missions

Thu, Nov 10, 2022

A radiation-tolerant version of Mercury Systems’ 8Gbyte DDR4 memory has been announced. According to the company, it “sets a new bar for performance in data-intensive processing applications in space”.

Today, military satellites enable critical national security missions such as missile warning, communications and Earth observation. Commercial satellites provide in-flight Wi-Fi connectivity, TV and radio services as well as global infrastructure and asset monitoring. These space systems require ever-increasing amounts of processing power to manage enormous volumes of data.

The increased complexity of these space systems, as capabilities and requirements are added, need high density memory capabilities to complement greater processing power. As space systems are increasingly developed with smaller form factors, Mercury’s 8GB DDR4 components offer 75 per cent space savings compared to alternative memory options, claimed the company.

“Mercury memory modules are designed to operate in the most demanding environments and are employed on critical missions in the air, land, and sea domains,” said Tom Smelker, vice president and general manager of custom microelectronics solutions at Mercury. These radiation-tolerant 8Gbyte DDR4 modules will unlock even more capability and performance for next-generation government and commercial space missions, he added.

Mercury’s 8Gbyte DDR4 memory components feature data transfer speeds of up to 2,666Mbits per second in a form factor that is 13 x 20 x 2.36mm. The memory package has eutectic solder balls for board-level reliability and the memory components undergo 100 per cent burn-in and electrical test for quality assurance.

The memory components are manufactured in a DMEA-trusted facility.

Mercury delivers commercial innovation to the global aerospace and defence industry, providing products, services and technologies and from data to decision, silicon to systems.
