DP83848-EP (ACTIVE) Enhanced Product PHYTER Extreme Temperature Single Port 10/100 Mb/s Ethernet Physical Layer



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. Our device meets IEEE 802.3u standards over a military temperature range of –55°C to 125°C. 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 all in a 48 pin PQFP package.

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.
