GENERAL DESCRIPTION  
The ezLINX iCoupler Isolated Interface Development  
environment provides developers with a cost-effective, plug and  
play method for evaluating 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.  
Isolated Physical layer communication standards are  
implemented using ADI's isolated transceivers with integrated  
iCoupler and isoPower technology. Included are 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

SYSTEM ARCHITECTURE  
SV(91), is added for additional functionality. The Ethernet  
option is not fitted on the standard ezLINX hardware.  
The system architecture Block diagram of the ezLINX hardware  
is shown in Figure 2. An extender connector, Hirose FX8 120P-  
Figure 2. ezLINX Hardware Block diagram  
The 5V supply is connected to VCC(pin 8) to power the  
isoPower isolated Power supply of the ADM3053. This  
generates an isolated 5V on the Visoout pin(pin 12) of the  
ADM3053 and needs to is connected to the Visoin pin(pin 19).  
The 3.3Vsupply is connected to the VIO pin(pin 6) to power the  
iCoupler signal isolation that needs to be compatible with the  
3.3V logic of the Blackfin ADSP-BF548. The RS pin(pin 18) is  
connected through a 0Ω resistor to CAN_ISO_GND in order to  
de-activate slew rate limiting,  
ISOLATED CAN  
The Isolated CAN port is implemented using the ADM3053  
Signal and Power isolated CAN transceiver. The ADM3053  
connects to CAN0 of the ADSP-BF548 and is capable of  
functioning at data rates of up to 1Mbit/s. Figure 3 shows a  
circuit diagram of the implementation of the ADM3053 on the  
ezLINX hardware.  
The CAN Node can be configured using jumpers JP17 and  
JP18. When both jumpers JP17 and JP18 is fitted, the CAN  
node is split terminated with 120Ω and a common mode  
capacitor o f 47nF. If termination is not required, remove JP17  
and JP18. Table x show jumper configurations for all the  
interfaces on ezLINX.  
A four pin screw terminal connector, J8 is used for easy access  
to the CANH(Pin 1), CANL(Pin 3) and CAN_ISO_GND(Pin 2  
and 4) connections.  
Application note AN-1123 provides more information on  
implementing CAN Nodes.

of 10kΩ will be connected. Table x show jumper configurations  
for all the interfaces on ezLINX.  
ISOLATED RS-485 AND RS-422  
The Isolated RS-485 and RS-422 port is implemented using the  
ADM2587E Signal and Power isolated CAN transceiver. The  
ADM2587E connects to UART2 of the ADSP-BF548 and is  
capable of functioning at data rates of up to 500kbit/s. Figure 4  
shows a circuit diagram of the implementation of the ADM3053  
on the ezLINX hardware.  
The 3.3V supply is connected to VCC(pin 2 and 8) to power the  
isoPower isolated Power supply and iCoupler signal isolation of  
the ADM2587E. This generates an isolated 3.3V on the Visoout  
pin(pin 12) of the ADM2587E and is connected to the Visoin  
pin(pin 19).  
The RS-485 Node can be configured using jumpers JP3, JP4,  
JP19 and JP40. To configure the node as a half-duplex RS-485  
node, connect JP3 and JP4. When JP3 and JP4 are fitted, it will  
connect A to Y and B to Z. When JP3 and JP4 are removed, the  
node will be configured as a full duplex RS-485 node or as a RS-  
422 node. When JP19 is fitted, the A and B pins will be  
A six pin screw terminal connector, J7 is used for easy access to  
the A(Pin 2), B(Pin 3), Z(Pin 4), Y(Pin 5) and RS-

technology.  
ISOLATED RS-232  
The Isolated RS-232 port is implemented using the ADM3252E  
Signal and Power isolated RS-232 transceiver. The ADM3252E  
connects to UART3 of the ADSP-BF548 and is capable of

ISOLATED SPI  
Two Isolated SPI ports are implemented using the ADuM3401,  
ADuM3402 iCoupler signal isolators and the ADuM5000  
isoPower Isolated DC to DC converter. The ADuM3401 of the  
isolate d SPI1 is connected to SPI0 of the ADSP-BF548. The  
ADuM3402 is used for isolating the SPI slave select lines. Figure  
8 shows a circuit diagram of the implementation of Isolated  
SPI1 using the ADuM3401, ADuM3402 and ADuM5000 on the  
ezLINX hardware.  
Two seven pin screw terminal connectors, J10 and J25 are used  
for easy access to the SPISCK(Pin 1), SPIMOSI(Pin 2),  
SPISEL1/SPISS(Pin 3), SPIMISO(Pin 4). SPISEL2(Pin 5),  
SPISEL3(Pin 6) and SPI_ISO_GND(Pin 7).  
To connect Isolated SPI1 as a master, connect jumpers JP5, JP7,  
JP9, JP11, JP13 and JP15 while leaving jumpers JP6, JP8, JP10,  
JP12, JP14 and JP16 open. To connect Isolated SPI1 as a slave,  
connect jumpers JP6, JP8, JP10, JP12, JP14 and JP16 while  
leaving jumpers JP5, JP11, JP13 and JP15 open.  
The ADuM3401 of the isolate d SPI2 is connected to SPI2 of the  
ADSP-BF548. The ADuM3402 is used for isolating the SPI slave  
select lines. Figure 9 shows a circuit diagram of the  
implementation of Isolated SPI2 using the ADuM3401,  
ADuM3402 and ADuM5000 on the ezLINX hardware.  
To connect Isolated SPI2 as a master, connect jumpers JP22,  
JP24, JP26, JP28, JP30 and JP32 while leaving jumpers JP23,  
JP25, JP27, JP29, JP31 and JP33 open. To connect Isolated SPI1  
as a slave, connect jumpers JP23, JP25, JP27, JP29, JP31 and
