open-in-new Find other Ethernet PHYs


The DP83847 is a full feature single Physical Layer device with integrated PMD sublayers to support both 10BASE-T and 100BASE-TX Ethernet protocols over Category 3 (10 Mb/s) or Category 5 unshielded twisted pair cables.

The DP83847 is designed for easy implementation of 10/100 Mb/s Ethernet home or office solutions. It interfaces to Twisted Pair media via an external transformer. This device interfaces directly to MAC devices through the IEEE 802.3u standard Media Independent Interface (MII) ensuring interoperability between products from different vendors.

The DP83847 utilizes on chip Digital Signal Processing (DSP) technology and digital Phase Lock Loops (PLLs) for robust performance under all operating conditions, enhanced noise immunity, and lower external component count when compared to analog solutions.
