High Temperature PHYTER single port 10/100 Mb/s Ethernet physical layer

 

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.
