Low power TCXO accelerates development through customisation

MEMS timing specialist, SiTime, announces the SiT5008 temperature-compensated silicon MEMS oscillator (TCXO). It is intended for connected consumer and IoT devices such as internet-connected audio-video, over-the-top streaming devices, industrial smart meters, and other devices that use low power wireless connectivity.

The SiT5008 offers programmable features, high reliability, and environmental resilience in a small package.

It is also an example of SiTime’s rapid release strategy, where the company develops up to 15 product derivatives from a single base platform.

“Each derivative has customised features and solves unique timing problems for customers,” explained Piyush Sevalia, executive vice president of marketing of SiTime.

The small, low power SiT5008 MEMS TCXO delivers any frequency between 10 and 60MHz accurate to six decimals and exhibits ±2 ppm to ±10 ppm frequency stability.

The TCXO has an LVCMOS output and an operating temperature range of -40 to +85 degrees C. It has a low power consumption of 3.5mA typical at 1.8V and features a standby mode for longer battery life.

The SiT5008 MEMS TCXO is supplied in an industry-standard 2.5 x 2.0mm package and is 100 per cent pin-compatible with quartz devices.

It is also RoHS and REACH-compliant, Pb-free, halogen-free, and antimony-free.

The SiT5008 TCXO is available in production now.

SiTime is a market leader in silicon MEMS timing. Its programmable solutions offer a rich feature set that enables customers to differentiate their products with higher performance, smaller size, lower power, and better reliability. The company has shipped over two billion devices.

2.3Mpixel HDR automotive video camera is ready for prototyping

Intended for prototyping and small series production of video and computer vision ADAS or autonomous driving systems, the logiCAM-FPD3-AR023 video camera is equipped with the HDR ISP video pipeline. It is also compatible with the latest automotive high-speed serial interfaces, says Xylon.

Xylon, is a Croatian company providing intellectual property (IP) cores, services and solutions based on programmable FPGA, SoC and ACAP devices. It also manufacturers flexible automotive HIL data logging. The logiCAM-FPD3-AR023 video camera has support for TI’s FPD-Link III serial interface.

The video camera features a 2.3Mpixel AR0231 RCCB video sensor from ON Semiconductor, a Xilinx Artix FPGA with an integrated Xylon logicBricks HDR ISP video pipeline, and TI’s FPD-Link III compatible serial interface. All this is integrated into a small, cubic inch big housing.

The camera outputs a quality colour image, and can be used for prototyping, as a reference camera for other camera systems in development, and as a sensor in different production systems.

Davor Kovacec, founder and CEO of Xylon, explained that the video cameras can be purchased in quantities ranging from a single piece to several thousand pieces, suitable for e.g. special vehicles video and vision applications.

Xylon also offers an equivalent video camera with the next generation GMSL serialiser from Maxim Integrated.

Both cameras join Xylon’s embedded hardware, reference designs and IP for video and vision developments based on Xilinx’ programmable devices. The collection includes development platforms, such as the logiVID-ZU vision development kit, based on Xilinx’ Zynq UltraScale+ MPSoC device, or the logiVID-ACAP kit, based on Xilinx’ Versal ACAP device. All development platforms come with a standard set of four automotive video cameras, and enable an immediate development of multi-camera applications.

Xylon focuses on design of flexible automotive data logging, IP cores and design services based on programmable FPGA and SoC/MPSoC devices. The company was founded in 1995, and provides embedded graphics, video and vision products.

Xylon is a Premier Member of the Xilinx Alliance Program.

Multi-Gbit Ethernet compliance test meets IEEE 802.3ch

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

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.
