DP83848J/M
The DP83848J/M addresses the quality, reliability and small form factor required for
space sensitive applications in embedded systems.
The DP83848J/M offers performance far exceeding the IEEE specifications, with superi-
or interoperability and industry leading performance beyond 137 m of Cat-V cable. They
also of
fer Auto-MDIX to remove cabling complications. DP83848J/M has superior ESD
protection, greater than 4 KV human body model, providing extremely high reliability
and robust operation, ensuring a high level performance in all applications.
