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.
