The DP83TC812-Q1 device is an IEEE 802.3bw compliant automotive PHYTER™ Ethernet physical-layer transceiver, which can work with an unshielded twisted-pair cable. The PHY supports TC10 sleep and wake features. PHY provides all physical layer functions necessary for transmitting and receiving data over unshielded, single, twisted-pair cables. The device provides xMII flexibility with support for standard MII, RMII, RGMII, and SGMII MAC interfaces. The PHY also integrates a low-pass filter on the MDI side to reduce emissions.

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 MDI, as well as providing real-time monitoring through the use of a programmable interrupt. Additionally, the DP83TC812-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 device is housed in a 6.00mm × 6.00mm, 36-pin VQFN wettable flank package. This device is pin-to-pin compatible with DP83TG720 (1000BASE-T1). The device is also form factor compatible with DP83TC811. This allows for using a single PCB layout for DP83TC811, DP83TC812, DP83TC814, and DP83TG720.
