DP83867IR, DP83867CR
SNLS484C â FEBRUARY 2015 â REVISED NOVEMBER 2015
9.1 Overview
The DP83867 is a fully featured Physical Layer transceiver with integrated PMD sublayers to support 10BASE-
Te, 100BASE-TX and 1000BASE-T Ethernet protocols.
The DP83867 is designed for easy implementation of 10/100/1000 Mbps Ethernet LANs. It interfaces directly to
twisted pair media via an external transformer. This device interfaces directly to the MAC layer through the IEEE
802.3u Standard Media Independent Interface (MII), the IEEE 802.3z Gigabit Media Independent Interface
(GMII), or Reduced GMII (RGMII).
The DP83867 provides precision clock synchronization, including a synchronous Ethernet clock output. It has
deterministic, low latency and provides IEEE 1588 Start of Frame Detection.
The DP83867 offers innovative diagnostic features including dynamic link quality monitoring for fault prediction
during normal operation. It can support up to 130m cable length.
