DP83848J PHYTER® Mini LS
Commercial Temperature Single Port 10/100 Ethernet Transceiver
General Description
Features
The DP83848J addresses the quality, reliability and small •
form factor required for space sensitive applications in _•
embedded systems.
•
The DP83848J offers performance far exceeding the IEEE
specifications, with superior interoperability and industry
•
leading performance beyond 137m of Cat-V cable. The ^•
DP83848J also offers Auto-MDIX to remove cabling com- •
plications. DP83848J has superior ESD protection, greater
than 4KV Human Body Model, providing extremely high
•
reliability and robust operation, ensuring a high level per- ^•
formance in all applications.
