Texas Instruments' DP83867 is a robust, low power, fully featured physical layer transceiver with integrated PMD sublayers to support 10BASE-Te, 100BASE-TX, and 1000BASE-T Ethernet protocols. Optimized for ESD protection, the DP83867 exceeds 8 kV IEC 61000-4-2 (direct contact). 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 reduced GMII (RGMII) or embedded clock serial GMII (SGMII).
The DP83867 provides precision clock synchronization, including a synchronous Ethernet clock output. It has low latency and provides IEEE 1588 start of frame detection. Designed for low power, the DP83867 consumes only 457 mW under full operating power. Wake on LAN can be used to lower system power consumption.
