Description The DP83848T PHYTER Mini addresses the quality, reliability and small form factor required for space sensitive applications in embedded systems operating in the industrial temperature range. The device offers performance far exceeding the IEEE specifications, with superior interoperability and industry leading performance beyond 137m of Cat-V cable. The DP83848T also offers Auto-MDIX to remove cabling complications. DP83848T has superior ESD protection, greater than 4KV Human Body Model, providing extremely high reliability and robust operation, ensuring a high level performance in all applications. Nationals DP83848T incorporates a number of system cost-reducing features not found on other suppliers Physical layer products. For example, the DP83848T incorporates a 25MHz clock out that eliminates the need and hence the space and cost, of an additional Media Access Control (MAC) clock source component. In addition, both MII and RMII are supported ensuring ease and flexibility of design. The DP83848T is offered in a tiny 6mm x 6mm LLP 40-pin package and is ideal for industrial controls, building/factory automation, transportation, test equipment and wireless base stations.

Note: The Early Failure Rates (EFR) were calculated as point estimate PPM based on rejects and sample size for EFR. The Long Term Failure Rates were calculated at 60% confidence using the Arrhenius equation at 0.7eV activation energy and derating the assumed stress temperature of 150°C to an application temperature of 55°C.
