Safety isolated CAN FD transceivers deliver 12Mbps “Future-Proof” networks

Looking to address the need for speed, functionality, isolation, and performance in industrial and building automation, energy systems, and mil/aero networks, Analog Devices, has announced an extension to its transceiver product line for controller area networks with flexible data-rate (CAN FD).

The galvanically isolated iCoupler digital isolation ADM3055E IC series not only meets, but exceeds the industry standard of 5 Mbps, offering 12 Mbps performance to support future needs, yet remaining fully backward compatible with existing CAN and CAN FD designs.

The reinforced ADM3055E also features a new, low radiated emissions isoPower isolated DC/DC converter as well as enhanced robustness, resulting in easier design-in and faster time-to-market for CAN nodes with full-safety isolation.

With the next-generation CAN FD ADM3055E series, designers can look to deliver increased data rates and longer cable lengths due to low loop delays (150 ns max) and extended common-mode range.

An integrated isolated DC/DC converter eliminates the need to provide a separate power source for the isolated bus side.

This combination of high level of integration, ease of obtaining emissions and ESD certifications, and the availability of integrated, isolated power allows designers to minimise development cost, PC-board footprint, and overall solution size, while avoiding the limitations of existing isolated products and approaches.

ADI said that versions with lower isolation ratings will be available soon.
