1 / 84 page © 2008 National Semiconductor Corporation www.national.com 1 May 2008 DP83848YB PHYTER® - Extreme Temperature Single Port 10/100 Mb/s Ethernet Physical Layer Transceiver General Description The number of applications requiring ethernet connec- tivity continues to increase. Along with this increased market demand is a change in application require- ments. The DP83848YB was designed to allow ether- net 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, automo- tive/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 pro- viding the flexibility allowing for ease of implementation by the end user. The DP83848YB features integrated sublayers to sup- port both 10BASE-T and 100BASE-TX Ethernet proto- cols, which ensures compatibility and interoperability with all other standards based Ethernet solutions.
