GENERAL DESCRIPTION
The ezLINX™ iCoupler® isolated interface development
environment provides developers with a cost-effective, plug
and play method for evaluating eight digitally isolated physical
layer communication standards (USB, RS-422, RS-485, RS-232,
CAN, SPI, I
2
C, and LVDS). The Blackfin® ADSP-BF548 processor
runs the uClinux® operating system and allows for easy customi-
zation 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 Analog
Devices, Inc., isolated transceivers with integrated iCoupler and
isoPower® digital isolator technology.
The hardware of the ezLINX iCoupler isolated interface develop-
ment environment contains the ADSP-BF548 Blackfin processor
with 64 MB of RAM and 32 MB of flash memory. The isolated
physical layer communication standards are implemented using
Analog Devices isolated transceivers with integrated iCoupler and
isoPower technology. Devices used to implement these isolated
physical layer communication standards include the following:
• Isolated USB using the ADuM3160
• Isolated CAN using the ADM3053 signal and power
isolated CAN transceiver
• Isolated RS-485 and RS-422 using the ADM2587E signal
and power isolated RS-485/RS-422 transceiver
• Isolated RS-232 using the ADM3252E signal and power
isolated RS-232 transceiver
• Isolated I
2
C using the ADuM1250 and ADuM5000
• Isolated SPI using the ADuM3401, ADuM3402, and
ADuM5000
• Isolated LVDS using the ADuM3442, ADuM5000,
ADN4663, and ADN4664
This evaluation board contains multiple parts with isoPower
technology, which uses high frequency switching elements to
transfer power through the transformer. Special care must be
taken during PCB layout to meet emissions standards. See the
AN-0971 Application Note, Recommendations for Control of
Radiated Emissions with isoPower Devices, for board layout
recommendations. The ezLINX PCB layout has not been verified
to pass radiated emissions specifications.
