Physical layer transceiver with integrated PMD sublayers for harsh environments

The rugged Texas Instruments DP83867 is a robust low-power fully-featured Physical Layer transceiver with integrated PMD sublayers to support 10BASE-T, 100BASE-TX and 1000BASE-T Ethernet protocols. Optimized for ESD protection, the device exceeds 8kV IEC 61000-4-2 (direct contact). Aimed at harsh industrial environments, the DP83867 consumes only 565mW under full operating power. For further power savings, there is an optional 1.8-V supply that can reduce power to 545mW. Wake on LAN can be used to lower system power consumption. The DP83867 is designed for easy implementation of 10/100/1000 Mb/s Ethernet LANs. It interfaces directly to twisted pair media via an external transformer. This device interfaces directly to the MAC layer through the IEEE 802.3 Standard Media Independent Interface (MII), the IEEE 802.3 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.
