Texas Instruments DP83TD510E IEEE 802.3CG 10BASE-T1L Ethernet PHY

Texas Instruments DP83TD510E IEEE 802.3CG 10BASE-T1L Ethernet PHY is an ultra-low power Ethernet physical layer transceiver compliant with the IEEE 802.3cg 10Base-T1L specification. The PHY has a very low noise coupled receiver architecture, enabling long cable reach and very low power dissipation. The DP83TD510E has external MDI termination to support intrinsic safety requirements. It interfaces with MAC layer through MII, Reduced MII (RMII), RGMII, and RMII low power 5MHz master mode. It also supports RMII back-to-back mode for applications that require cable reach extension beyond 2000 meters. It supports a 25MHz reference clock output to clock other modules on the system. The Texas Instruments DP83TD510E offers integrated cable diagnostic tools with built-in self-test and loopback capabilities for ease of design or debug.
