Adapter board allows machine learning based sensor fusion

The latest addition to Rutronik System Solutions’ board family is the RAB1 – Sensorfusion. The adapter board offers its own platform that allows machine learning (ML) -based sensor fusion, which forms the basis and the future of artificial intelligence (AI).

It is equipped with sensors from Infineon, Bosch SE and Sensirion. (All sensors are also available in Rutronik’s product portfolio.) 

It can be used as a development tool to shorten time to market for a range of applications of sensor fusion, such as air quality measurement or smoke and gas detectors. 

Combining and linking different measured values from several sensors, or sensor fusion, is important to gain information, explained Rutronik. The RAB1 Sensorfusion board allows developers to test and select the most suitable components or combination of sensors for an application. The board features the DPS310 barometric air pressure sensor from Infineon, the BMI270 IMU and the BME688 intelligent gas sensor from Bosch Sensortec and the SGP40-D-R4 and the SHT41-AD1B-R2 temperature and humidity sensor from Sensirion. These components can be tested individually or in combination using the board. Rutronik System Solutions provides the software including various application examples. It also has an Arduino interface for use with all other boards, including the Rutronik Basis Board RDK2. 

Rutronik Elektronische Bauelemente was founded in 1973 and is an independent family-owned company.

The broad product portfolio includes semiconductors, passive and electromechanical components as well as embedded boards, storage and displays, and wireless products. The company has product areas in the Rutronik Automotive, Rutronik Embedded, Rutronik Power and Rutornik Smart divisions with both specific products and services tailored to the respective applications. 

Competent technical support for product development and design-in up to the research area, individual logistics and supply chain management as well as comprehensive services are available.

Automotive GbE switch with optical ports is an industry first, says KDPOF

The EVB9351-AUT-SW-NXP with five 1000BASE-RH optical ports is an industry first, claimed KDPOF. It comprises the company’s KD9351 FOT (fibre optic transceiver) and KD1053 PHY IC. The core of the high-speed switch platform is the NXP SJA1110 SoC, commented Guenter Sporer, director of marketing, systems and applications of automotive Ethernet solutions at NXP Semiconductors.

The SJA1110 is a four pin-compatible and software-compatible automotive Ethernet switch SoC. KDPOF’s evaluation board supports carmakers and suppliers in delivering high speed connectivity essential for autonomous vehicles. 

The EVB9351-AUT-SW-NXP automotive Ethernet switch board has two SJA1110 switches from NXP. The SoC integrates an Arm Cortex-M7 at 200MHz processor for autonomous and secure operation. It has 512kbyte integrated SRAM as instruction tightly coupled memory (ITCM) and 256kbyte integrated SRAM as data tightly coupled memory (DTCM). It contains a double precision floating point unit and a memory protection unit. Boot time is less than 100ms with a 512kbyte firmware with authentication. 

The switch has selectable I/O voltages (1.8, 2.5 and 3.3V) to aid in design flexibility. Its footprint is just 14 x 14mm (LFBGA256) and a package with 0.8mm pitch. 

The switch is automotive AEC-Q100 qualified, compliant with ISO 26262 and ASIL-B. 2.5Gbits per second operation is supported for two SGMII ports. The board has five optical 1000/100BASE-RH ports, 12 100BASE-T1 ports, and one NXP SABRE expansion connector.

With the KD9351 optical interface, KDPOF complements the KD1053 digital interface IC, providing a full optical port for in-vehicle gigabit connectivity. The assembly of the FOT and the IC is simplified, explained KDPOF. The connector has snap-fit without soldering. 

The devices form a complete automotive 1000BASE-RHC physical layer. KDPOF explained that constructing the trans-impedance amplifier, photodiode, LED driver and LED as one single device significantly lowers costs. 

Optical Ethernet connectivity solves the challenges and electrical interference in vehicles thanks to its EMC, reliability and low cost. The optical Ethernet connectivity can be used in safe Ethernet backbones, smart antenna modules and sensor connections for ADAS (advanced driver assistance systems) and audio/video.

Fabless semiconductor supplier KDPOF provides high speed optical networking for harsh environments. KDPOF made Gbit communications overstep-index plastic optical fibre (SI-POF) a reality for automotive design. 

Founded in 2010 in Madrid, Spain, KDPOF offers its technology as a fully qualified automotive-grade ASSP.

R&S FE170 D band frontend extensions enable sub-THz research  

At EuMW (European Microwave Week) Rohde & Schwarz will present a signal generation and analyser for measurements in the D band that, the company said will “significantly simplify early next generation mobile communications research”.

The The R&S FE170ST (single transmit) and R&S FE170SR (single receive) front end extensions are easy to mount to, and configure with, the R&S SMW200A vector signal generator and the R&S FSW signal and spectrum analyser. The extensions will allow these two instruments to cover frequency ranges between 110 and 170GHz which are key spectrum for beyond 5G, for 6G technology and for future automotive radar applications, pointed out the company.

A test set up for sub-THz research using the R&S SMW200A and R&S FSW can be configured using just three connections (IF, reference frequency and LAN) to integrate the front ends into the base units. All users have to do is enter the IP address in the user interface of the base units. After connection, the front ends are directly controlled by the R&S SMW200A and R&S FSW, because the front ends’ control unit is integrated in their firmware. 

The front ends are compact with a form factor of 152 x 190 x 50mm. In addition, the internal synthesiser provides a local oscillator (LO) so the test set up does not need an additional analogue signal source for “excellent phase noise performance”. 

Rohde & Schwarz also offers smart accessories such as bandpass filters and TX power amplifiers.

The R&S FE170ST and R&S FE170SR frontend solution for D band research will be available by the end of 2022. 

Rohde  & Schwarz is exhibiting at EuMW 2022 (27 to 29 September) at the Milano Convention Centre, Italy, stand number D18.

224G Ethernet test suite validates digital interface technology

At this week’s ECOC (European Conference on Optical Communication) in Basel, Switzerland, Keysight and Synopsys demonstrated the industry’s first common electrical interface (CEI) SoC supporting 224Gbits per second.

To accelerate 1.6Tbit per second transceiver designs and pathfinding, Keysight Technologies has introduced 224G Ethernet test products which enable SoC makers to validate next-generation electrical interface technology, said the company, accelerating 1.6Tbit per second transceiver design and pathfinding.

In response to the bandwidth demands in networks and data centres generated b y 5G, AI and IoT, there is a requirement for high speed digital interfaces that support 224Gbits per second, per lane data connection speeds for increased bandwidths and to underpin 1.6Tbit per second interconnect technology, said Keysight. Improved data throughput and efficiency in data centre networks also contribute to reductions in power consumption and cost. Keysight believes it is the only provider of bit error ratio testers (BERTs) capable of generating and analysing 224Gbit per second signals.

This portfolio includes the M8050A BERT, offering 224Gbit per second testing for electrical design and validation of transceiver SoCs used in data centres and networks for transferring large amounts of data at high speeds. It provides signal integrity that enables accurate characterisation of receivers used in next-generation data centre networks and server interfaces, said Keysight. 

Synopsys used the M8050A BERT, M8199 arbitrary waveform generator (AWG) and Infiniium UXR-series oscilloscope to develop and validate 224G serialiser / deserialiser (SerDes) IP designs.

“High-performance computing systems depend on high-speed, low-latency interfaces to process massive amounts of data with minimal power,” said John Koeter, senior vice president of marketing and strategy for the Solutions Group at Synopsys. The high speed Ethernet IP provided used Keysight’s digital interface test to validate the performance of the PHY IP. As a result, designers could meet their design and system-level requirements for high-performance computing, networking and AI SoCs, said Koeter.
