This device is ideally suited for industrial and motor control, building/factory automation, automotive and test equipment applications. The DP83848H is designed from ground up for extreme temperature performance, with a thermally efficient pack- age ensuring reliable operation over an operating range of -40C to 125C. Rigorously tested at both low temperature and high temperature extremes, the device is ideal for out- door environments and demanding factory floor conditions. The device offers performance beyond the IEEE specifica- tions, with superior interoperability and industry leading performance. The DP83848H offers Auto-MDIX to remove cabling complications, superior ESD protection of greater than 4KV HBM for greater reliability, and superior cable length operation (greater than 137m) to provide a high level of performance in all applications. A number of system cost-reducing features have been integrated that are not commonly found in other Ethernet Physical layer products (PHYs). For example, the DP83848H offers a 25MHz clock out that eliminates the need and hence the space and cost, of an additional Media Access Control (MAC) clock source component. DP83848H is offered in a small 6mm x 6mm LLP 40-pin package. System Diagram PHYTER® is a registered trademark of National Semiconductor Corporation.
