4.4 Transceivers
The transceivers are Analog Devices ADM3053 combination isolation and transceiver. It provides is5V to
power the isolated side of the transceiver. This is5V is available on the I/O connector.
4.5 Isolation
The module supports 500V isolation between each CAN port and the host, and between each CAN port and the
other, via the ADM3053 isolated transceiver. An optional high-voltage resistor can be installed across each
isolation barrier to enable leakage current flow between the isolated transceiver grounds and the host ground.
4.6 Power Supply
The module is powered by +3.3V from the PCIe MiniCard socket. It provides all other required voltages on board,
inc5V for the CAN transceivers and the FPGA core voltages.
5. INSTALLATION
The DS-MPE-CAN2L plugs in to any socket meeting the PCIe MiniCard specifications. It has two connectors,
one for each pair of serial ports, a protocol configuration jumper block, and a pair of mounting holes. To install the
DS-MPE-CAN2L, fully insert the board into a PCIe MiniCard connector and secure in place by inserting one screw
from the hardware kit into each of the mounting holes, see the diagram below.
