DescriptionThe number of applications requiring ethernet connectivity continues to increase. Along with this increased market demand is a change in application requirements. The DP83848YB was designed to allow ethernet connectivity in the harshest environments. Our device meets IEEE 802.3u standards over an EXTREME temperature range of -40°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 DP83848YB 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 LQFP package.
With the DP83848YB NATIONAL continues to build on its Ethernet expertise and leadership position by providing the flexibility allowing for ease of implementation by the end user.
The DP83848YB 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.
