DP83848K PHYTER® Mini LS
Industrial Temperature Single Port 10/100 Ethernet Transceiver
General Description
Features
The DP83848K addresses the quality, reliability and small •
form factor required for space sensitive applications in _•
embedded systems operating in the industrial temperature
range.
•
The DP83848K offers performance far exceeding the ^•
IEEE specifications, with superior interoperability and ^•
industry leading performance beyond 137m of Cat-V •
cable. The DP83848K also offers Auto-MDIX to remove
cabling complications. DP83848K has superior ESD pro-
•
tection, greater than 4KV Human Body Model, providing ^•
extremely high reliability and robust operation, ensuring a •
high level performance in all applications.
•
DP83848K offers two flexible LED indicators - one for Link _•
and the other for Speed. In addition, both MII and RMII are
supported ensuring ease and flexibility of design.
