The DP83TC811-Q1 device is an IEEE 802.3bw-compliant automotive PHYTER™ Ethernet physical layer transceiver. The device provides all physical layer functions needed to transmit and receive data over unshielded single twisted-pair cables. The device provides xMII flexibility with support for standard MII, RMII, RGMII, and SGMII MAC interfaces.

This device includes the Diagnostic Tool Kit, providing an extensive list of real-time monitoring tools, debug tools and test modes. Within the tool kit is the first integrated electrostatic discharge (ESD) monitoring tool. The tool is capable of counting ESD events on both the xMII and MDI as well as providing real-time monitoring through the use of a programmable interrupt. Additionally, the DP83TC811-Q1 includes a pseudo random binary sequence (PRBS) frame generation tool, which is fully compatible with internal loopbacks, to transmit and receive data without the use of a MAC. The DP83TC811-Q1 is housed in a 6.00mm × 6.00mm, 36-pin VQFN wettable flank package.
