Overview
The DP83867ISRGZT is a robust, low-power, fully featured Physical Layer transceiver developed by Texas Instruments. This device is designed to support 10BASE-Te, 100BASE-TX, and 1000BASE-T Ethernet protocols, making it suitable for a wide range of Ethernet LAN implementations. It features integrated PMD sublayers and is optimized for high ESD protection, exceeding 8kV IEC 61000-4-2 (direct contact) standards. The DP83867ISRGZT interfaces directly to twisted pair media through an external transformer and to the MAC layer via Reduced GMII (RGMII) or embedded clock Serial GMII (SGMII). It provides precision clock synchronization, including a synchronous Ethernet clock output, and supports low latency and IEEE 1588 Start of Frame Detection.
