3 Description

The number of applications requiring ethernet

connectivity continues to increase. Along with this

increased market demand is a change in application

requirements. The DP83848 was designed to allow

ethernet connectivity in the harshest environments.

This device is ideally suited for harsh environments

for example wireless remote base stations,

automotive, transportation and industrial control

applications.

The DP83848 is a highly-reliable, feature-rich robust

device which includes enhanced ESD protection, MII

and RMII for maximum flexibility in MPU selection.

The DP83848 features integrated sublayers to

support both 10BASE-T and 100BASE-TX Ethernet

protocols, which ensures compatibility and

interoperability with all other standards based

Ethernet solutions.
