Overview
The DP83867CRRGZT is a robust, low-power, fully featured Physical Layer transceiver designed by Texas Instruments. This device supports 10BASE-Te, 100BASE-TX, and 1000BASE-T Ethernet protocols, making it suitable for a wide range of Ethernet LAN implementations. It is optimized for high immunity and low power consumption, with a power usage of 457mW under full operating conditions. The DP83867CRRGZT interfaces directly to twisted pair media via an external transformer and supports various MAC interfaces including MII, GMII, and RGMII. It is particularly notable for its ultra-low RGMII latency and compliance with Time Sensitive Network (TSN) standards.
