Overview
The DP83867ISRGZR is a robust, low-power, fully featured Physical Layer transceiver produced by Texas Instruments. It is designed to support 10BASE-Te, 100BASE-TX, and 1000BASE-T Ethernet protocols. This device is optimized for easy implementation of 10/100/1000Mbps Ethernet LANs and interfaces directly to twisted pair media through an external transformer. It also interfaces directly to the MAC layer through Reduced GMII (RGMII) or embedded clock Serial GMII (SGMII).
