Analog Devices’ Latest Safety Isolated CAN FD Transceivers Deliver 12 Mbps

Aiming to address the need for speed, functionality, isolation, and performance in industrial and building automation, energy systems, and mil/aero networks, Analog Devices, Inc. extended its transceiver product line for controller area networks with flexible data-rate (CAN FD). The galvanically isolated iCoupler® digital isolation ADM3055E IC series exceeds the industry standard of 5 Mbps with 12 Mbps performance, and it is 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.

ADM3055E Series Product Highlights:

• EN 55022/CISPR 22 Class B emissions standards on a two-layer PCB
• IEC61000-4-2 Level 4 ESD rating (±8 kV contact / ±15 kV air)
• ±40 V bus fault protection on CAN bus pins
• ±25 V common-mode range.
• 5V logic-side V_CC with isolated-side V_IO options for 1.8V, 2.5V, 3.3V and 5.0V supplies

With the CAN FD ADM3055E series, designers can realize 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 integration, ease of obtaining emissions and ESD certifications, and the availability of integrated, isolated power allows designers to minimize development cost, PC-board footprint, and overall solution size, while avoiding the limitations of existing isolated products and approaches. Versions with lower isolation ratings will be available soon.
