General Description


The DP83848K addresses the quality, reliability and small form factor required for space sensitive applications in embedded systems operating in the industrial temperature range.

The DP83848K offers performance far exceeding the IEEE specifications, with superior interoperability and industry leading performance beyond 137m of Cat-V cable. The DP83848K also offers Auto-MDIX to remove cabling complications. DP83848K 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.

DP83848K offers two flexible LED indicators - one for Link and the other for Speed. In addition, both MII and RMII are supported ensuring ease and flexibility of design.

A 25MHz clock out that eliminates the need and hence the space and cost, of an additional Media Access Control (MAC) clock source component is available only in DP83848T.

The DP83848K is offered in a tiny 6mm x 6mm LLP 40-pin package and is ideal for industrial controls, building/factory automation, transportation and 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.
