3 Description

The DP83867 device is a robust, low power, fully

featured Physical Layer transceiver with integrated

PMD sublayers to support 10BASE-Te, 100BASETX

and 1000BASE-T Ethernet protocols. Optimized

for ESD protection, the DP83867 exceeds 8kV IEC

61000-4-2 (direct contact).

The DP83867 is designed for easy implementation

of 10/100/1000Mbps Ethernet LANs. DP83867

interfaces directly to twisted pair media through 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. DP83867 has low latency and provides

IEEE 1588 Start of Frame Detection.

Designed for low power, the DP83867 consumes only

457mW under full operating power. Wake-on-LAN can

be used to lower system power consumption.
