Robust low-power fully-featured transceiver supports Ethernet protocols

The DP83867 is a robust new low-power fully-featured physical-layer transceiver from Texas Instruments (TI). The device integrates PMD sublayers to support 10BASE-T, 100BASE-TX and 1000BASE-T Ethernet protocols. Optimized for ESD protection, the DP83867 exceeds 8kV IEC 61000-4-2 (direct contact). The DP83867 consumes only 565mW under full operating power. For further power savings, there is an optional 1.8V 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, says the company.
