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 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. DP83867 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.
