Multi-Gbit Ethernet compliance test meets IEEE 802.3ch

Thu, Feb 04, 2021

Believed to be the first multi automotive Gbit Ethernet compliance tester, the TekExpress has been released by Tektronix.

It confirms the integrity of faster signals to achieve higher data transfer rates and enable advanced technologies to meet the requirements of complex automotive designs. Newer automotive technologies, such as autonomous driving, 5G and connected cars, require a vast amount of data necessary and must be tested to ensure reliable transfers between a vehicle’s electronic sub-systems.

The automated compliance test application allows for quick, accurate and reliable validation and debugging for multi-Gbit Ethernet chipsets and electronic control units (ECUs) to meet physical media attachment (PMA) transmitter measurement requirements for up to 10Gbits per second.

The Tektronix TekExpress multi-Gbit automotive Ethernet compliance test solution is fully automated and meets the current version of the IEEE 802.3ch MultiGBASE-T1 specification.

“Multi-gigabit Ethernet uses PAM4 modulation to achieve high data rates and reliability, pushing the boundaries of signal integrity and requiring higher performance measurements for compliance, debugging and validation. Debug tools like DPOJET and PAM4 analysis also allow for quick identification of the root cause of a failure,” said Raajit Lall, general manager of Market Solutions at Tektronix.

The Tektronix TekExpress multi-Gbit automotive Ethernet compliance test solution is part of its family of automated compliance solutions for automotive Ethernet, and it works seamlessly with Tektronix oscilloscopes. It uses the TekExpress automation framework which means that engineers do not have to learn a new software interface.

This new application enhances Tektronix’s in-vehicle network offering of 10BASE-T1S, 100-BASE-T1 and 1000BASE-T1 compliance testing applications for automotive Ethernet standards.

The Tektronix IEEE 802.3ch Multi-Gigabit Ethernet automated compliance application is now available globally for 10G/5G/2.5GBASE-T1 automotive Ethernet PMA transmitter compliance testing on DPO70000 SX/DX series oscilloscopes.

Tektronix is an active participant in the Open Alliance, developing in-vehicle network test specifications and methodologies for reliable, cost-effective testing.

The company is headquartered in Beaverton, Oregon, USA. It specialises in test, measurement and monitoring solutions.

Maxim claims MAX17852 is first ASIL-D-compliant data acquisition system

Wed, Feb 03, 2021

Claimed to be the industry’s first data acquisition system to achieve ASIL-D compliance for voltage, current, temperature and communication of a battery management system, the MAX17852 battery monitor IC from Maxim Integrated offers both cost and space savings.

The MAX17852 14-channel, high-voltage, ASIL-D data-acquisition system is for use by designers of automotive battery management systems (BMS).

The 14-channel battery data acquisition system integrates a current sense amplifier so that current information is acquired at the same time as cell voltage and temperature. The MAX17852 allows both hall effect sensor and shunt resistors to be used as sensing components.

It is designed to be integrated into electric vehicles, hybrid electric vehicles and other transportation systems and can also be used for smart junction boxes, 48V and other automotive battery systems which can realise voltages of 400V and beyond.

OEMs and electric vehicle manufacturers require that all battery systems meet the highest safety requirements set by the ISO26262 guidelines. Through diagnostics and a safety-driven architecture, the MAX17852 enables customers to design systems to meet the highest ASIL-D standards for voltage, current, temperature and communication. It is claimed to offer the highest accuracy for delivering voltage, current and temperature data with tight time synchronisation. It allows a typical cell voltage measurement of ±0.45mV at room temperature and a maximum of ±2mV error in a temperature range of 5.0 to 40 degrees C, enabling car OEMs to get the most mileage range out of batteries. With a current sense amplifier capability of ±300mV, and a gain setting up to 256 times and 0.3 per cent current sense gain error, the MAX17852 provides the fastest, most accurate data for calculating power management, state of health and state of charge, says Maxim.

The high level of integration enables up to 16 per cent smaller form factor than a discrete solution to save board space. The integrated current sense amplifier provides up to 20 per cent cost savings.

The MAX17852 is available now. Maxim Integrated also offers the MAX17852EVKIT# evaluation kit.

Based on Nvidia’s Jetson TX2, the BoxPC EC-3200 is the latest compact embedded PC for use in industry, medical technology and smart cities. The industrial embedded PC is by iBase and available from TFT flat screen specialist, Distec.

The industrial embedded BoxPC EC-3200 is for applications with artificial intelligence (AI). It is based on the energy saving and powerful Nvidia Jetson TX2 processor. This fast and energy efficient processor has a dual core Denver 2 and a quad core Arm Cortex-A57 processor. “Compared to the Jetson TX1, the energy efficiency and performance has more than doubled,” explained Thomas Schrefel, product manager for Embedded at Distec. This is due to the Nvidia Pascal architecture with 256 processing units and up to 1.33T floating operations per second (TFLOPS). The EC-3200 is able to offer real AI computing power for edge applications with 8Gbyte memory and 59.7Gbyet per second memory bandwidth, he continued.

The robust design of the EC-3200 makes it suitable for use in industrial robots, medical devices, and smart cities and for devices that support collaboration in companies, said Distec.

For edge- and cloud-based AI products which require computing performance and video analysis to perform real time data processing and to overcome latency problems, the EC-3200 uses the Jetson TX2’s GPU-accelerated parallel processing to handle data-intensive and mission-critical workloads, such as deep learning applications.

The fanless EC-3200 is designed for uninterrupted operation and an extended temperature range from -20 to +60 degrees C. The Jetson TX2 has low power consumption, and is claimed to be 25 times more energy efficient than comparable desktop graphics processors.

The compact EC-3200 has 8Gbyte LPDDR4 memory and 32Gbyte eMMC. HDMI, Gigabit Ethernet, two USB 3.0 and two USB 2.0 ports are available as I/O interfaces.

The housing has a DB9 connection for RS232 or CAN bus, a micro USB slot and an external 10-pin GPIO connection. Two M.2 expansion sockets are available for expansion with optional SSD storage (2280 Key-M) and WAN modules (3042 Key-E). The operating system is based on a specially made Ubuntu 16.04 with Jetpack 3.2.1 and L4T 28.2.
