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. 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 QFP

package supports MII/GMII/RGMII whereas the QFN

package supports RGMII.

The DP83867 provides precision clock

synchronization, including a synchronous Ethernet

clock output. It has low latency and provides IEEE

1588 Start of Frame Detection.

The DP83867 consumes only 490mW (PAP) and

457mW (RGZ) under full operating power. Wake

on LAN can be used to lower system power

consumption.
