Signal and Power Isolated CAN Transceiver with Integrated Isolated DC-to-DC Converter
The ADM3053 is an isolated controller area network (CAN) physical layer transceiver with an integrated isolated dc-to-dc converter. The ADM3053 complies with the ISO 11898 standard.
The device employs Analog Devices, Inc., iCoupler® technology to combine a 2-channel isolator, a CAN transceiver, and Analog Devices isoPower® dc-to-dc converter into a single SOIC surface mount package. An on-chip oscillator outputs a pair of square waveforms that drive an internal transformer to provide isolated power. The device is powered by a single 5 V supply realizing a fully isolated CAN solution.
The ADM3053 creates a fully isolated interface between the CAN protocol controller and the physical layer bus. It is capable of running at data rates of up to 1 Mbps.
The device has current limiting and thermal shutdown features to protect against output short circuits. The part is fully specified over the industrial temperature range and is available in a 20-lead, wide-body SOIC package.
The ADM3053 contains isoPower technology that uses high frequency switching elements to transfer power through the transformer. Special care must be taken during printed circuit board (PCB) layout to meet emissions standards. Refer to the AN-0971 Application Note, Control of Radiated Emissions with isoPower Devices, for details on board layout considerations.

This product has been released to the market. The data sheet contains all final specifications and operating conditions. For new designs, ADI recommends utilization of these products.
The EVAL-ADM3053EBZ allows easy evaluation of the ADM3053 signal and power isolated CAN transceivers. The evaluation board allows all of the input and output functions to be exercised without the need for external components.The device employs Analog Devices, Inc., iCoupler® technology to combine a 2-channel isolator, a CAN transceiver, and an Analog Devices, Inc., isoPower® dc-to-dc converter into a single SOIC surface-mount package.

The ezLINX™ iCoupler® Isolated Interface Development Environment provides developers with a cost-effective, plug and play method for evaluation eight physical layer, digitally-isolated communication standards (USB, RS-422, RS-485, RS-232, CAN, SPI, I2C, and LVDS). The Blackfin® ADSP-BF548 processor is used to run the uCLinux operating system and allows for easy customization through the open source hardware and software platform. Development time is significantly reduced for embedded designers and system architects who are designing and evaluating isolated communication standards. The interfaces on ezLINX use ADI's isolated transceivers with integrated iCoupler® and isoPower® digital isolator technology.
The ADSP-CM403F EZ-KIT Lite and ADSP-CM408F EZ-KIT Lite include all hardware necessary to immediately begin evaluation.
- The ADSP-CM403F EZ-Board™ (for evaluating ADSP-CM402F & ADSP-CM403F) and the ADSP-CM408F EZ-Board™ (for evaluating ADSP-CM407F & ADSP-CM408F).
- The J-LINK LITE ARM debug probe from Segger.
The ADSP-CM403F EZ-Board and the ADSP-CM408F EZ-Board can also be purchased separately, if a debug probe is already available to the customer.
The ADSP-CM40x Board Design Database contains all of the electronic information required for the design, layout, fabrication and assembly of the ADSP-CM40x EZ-Boards, and is available to download from the Products Download area on this page.
Two expansion connectors are available for connecting probing boards that extend the system’s evaluation capabilities:
- Analog 120-Pin Probing Board - The board provides probing points for any analog signal of the 120-pin expansion interface connector.
- PWM 180-Pin Probing Board - The board provides probing points for any PWM/digital signal of the 180-pin expansion interface connector.
The probing boards are available separately as daughter boards that plug onto the ADSP-CM403F or
IAR Embedded Workbench is a complete high-performance C/C++ compiler and debugger toolchain that incorporates a compiler, an assembler, a linker and a debugger into one easy-to-use IDE. It is required for development and purchased directly from IAR Systems. Free evaluation versions are available for download.
The CM40x Enablement Software package provides C language programming environment and Application Programming Interface (API) supporting a quick and easy functional interface to the Analog’s ADSP-CM40x mixed-signal control processor family products. The API abstracts the low-level details of various peripherals (Controller Registers, DMA Engine and Interrupt Controller) into a simple, easy-to-use programming model. It comes in source form with various example programs to shorten your application’s time to market. Current and future versions of the software are available free of charge and always downloadable from here.
The software and documentation pack for the J-Link LITE ARM is available directly from Segger and requires entry of the serial number displayed on the back of the probe to activate it.
For applications that require use of the Ethernet or USB peripherals, the ADZS-CM40x family is supported by Micrium's uC/TCP-IP™ and uC/USB Device™ ARM M-Series solutions. Both of these items require use of uC/OS-III® RTOS and all must be purchased directly from Micrium.,The ADSP-CM40x mixed-signal control processor family is based on the ARM®Cortex®-M4 core and is designed for motor control and industrial applications.
