DP83848YB
DP83848YB is PHYTER - Extreme Temperature Single Port 10/100 Mb/s Ethernet Physical Layer Transceiver manufactured by National Semiconductor.
Description
The 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.
