General Description
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.
The DP83848K is offered in a tiny 6mm x 6mm LLP 40-pin
package and is ideal for industrial controls, building/factory
automation, transportation, test equipment and wireless
base stations.
