3 Description
The 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 8kV 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 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.
