Texas Instruments DP83867IR/DP83867CR Ethernet PHY Transceivers

Texas Instruments DP83867IR/DP83867CR Ethernet PHY Transceivers are robust, low-power, fully featured Physical Layer (PHY) transceivers with integrated PMD sublayers to support 1000BASE-T, 10BASE-Te, and 100BASE-TX Ethernet protocols. The DP83867IR/DP83867CR exceeds 8kV IEC 61000-4-2 (direct contact) and is optimized for ESD protection.

The DP83867IR/DP83867CR is designed to implement 10/100/1000Mbps Ethernet LANs easily. It interfaces directly to twisted pair media via an external transformer and directly to the MAC layer through the IEEE 802.3 Gigabit Media Independent Interface (GMII), the IEEE 802.3 Standard Media Independent Interface (MII), or Reduced GMII (RGMII). The QFP package supports GMII/MII/RGMII, whereas the QFN package supports RGMII.

The Texas Instruments DP83867IR/DP83867CR synchronizes precision clocks, including a synchronous Ethernet clock output. It provides IEEE 1588 Start of Frame Detection and has low latency. Under full operating power, the DP83867IR/DP83867CR consumes only 490mW (PAP) and 457mW (RGZ). Wake on LAN can be used to lower system power consumption.
