Protocol trigger and decode software accelerates CAN bus development

Engineers can verify and debug CAN XL and other automotive protocols using the D9010AUTP oscilloscope-based automotive protocol trigger / decode option by Keysight Technologies.

D9010AUTP covers CAN XL (controller area network extra long) to verify and debug low-speed automotive serial bus protocols and simplify the development and troubleshooting of systems including CAN / CAN FD (flexible data rate) and CAN XL.

CAN XL is the third-generation CAN standard in development by the CAN in Automation (CiA) group which increases payload data and bit rate of the established CAN FD protocol. The CAN XL data phase speed is specified to reach 10Mbits per second or more, depending on the transceiver capabilities and physical layer components. CAN XL has two modes of operation – fast mode and SIC (slow) mode.

Keysight’s automotive decoder software triggers and decodes the SIC mode signal in the arbitration phase, as well as the fast mode signal in the data phase. It also handles the CAN XL protocols implemented with the CAN HS / FD / SIC transceivers.

In-vehicle networking is pivotal for transmitting data quickly and reliably from sensors to AI decision making units, as well as between safety relevant electronic control units and electronic systems, explains Thomas Goetzl, vice president and general manager for Keysight’s automotive and energy solutions business unit. 

Keysight’s D9010AUTP software is compatible with Keysight’s Infiniium oscilloscopes using software version 11.30 or higher for MXR / EXR / UXR models and version 6.72 or higher for other Infiniium scope models. The combination allows users to set up the oscilloscope to show CAN, LIN, CAN-FD, CAN XL, FlexRay and SENT protocol decode in less than 30 seconds and gain access to integrated protocol-level triggers. The offering also saves time and eliminates errors by viewing packets at the protocol level, advises Keysight while the use of time-correlated views can quickly troubleshoot serial protocol problems back to the timing or signal integrity root cause.

Common source dual GaN FET is AEC-qualified for lidar systems

The latest addition to Efficient Power Conversion (EPC)’s family of automotive qualified transistors and ICs is small enough for time-of-flight (ToF) lidar applications including robotics, drones, 3D sensing and autonomous cars.

The EPC2221 is a common source dual GaN FET rated at 100V, 58 mOhm and 20A pulsed current. The FET can be also be used in surveillance systems and vacuum cleaners.

The low inductance and capacitance of the EPC2221 allows fast switching (100MHz) and narrow pulse widths (two nanoseconds) for high resolution and high efficiency.  Additionally, the small size (1.35 x 1.35mm) reduces PCB cost and total solution size, says EPC. 

This latest member of EPC’s family of GaN transistors and ICs designed to meet the performance and reliability standards of demanding automotive applications has completed AEC Q101 qualification testing including humidity testing with bias (H3TRB), high temperature reverse bias (HTRB), high temperature gate bias (HTGB), and temperature cycling (TC). 

In addition to lidar in automotive applications, the EPC2221 is suited to high-frequency DC/DC conversion, wireless power applications and synchronous rectification.

Alex Lidow, CEO and co-founder of EPC, believes this IC “improves the performance while reducing size and cost for time-of-flight lidar systems.”

The EPC2221 is available for immediate delivery from Digi-Key Electronics. 

Designers interested in replacing silicon MOSFETs with a GaN device can use the EPC GaN Power Bench’s cross reference tool to find a suggested replacement based on operating conditions.  

EPC specialises in enhancement mode GaN-based power management. The company says eGaN FETs and ICs provide performance many times greater than the best silicon power MOSFETs in applications such as DC/DC converters, remote sensing technology (lidar), motor drives for eMobility, robotics, and drones and low-cost satellites

EPC will be at PCIM Europe (10–12 May 2022) Hall 9 – Stand 113
