Low-power automotive Ethernet features a full diagnostic toolkit

The DP83TC811R-Q1 device, from Texas Instruments, is an IEEE 802.3bw-compliant automotive PHYTER Ethernet physical layer transceiver. It offers all physical layer functions required to transmit and receive data over unshielded single twisted-pair cables. The device gives xMII flexibility with support for standard MII, RMII, and RGMII MAC interfaces. This device comprises the Diagnostic Toolkit, giving an extensive list of real-time monitoring tools, debug tools and test modes. Within the toolkit is the first integrated ESD monitoring tool. It is capable of counting ESD events on both the xMII and MDI as well as offering real-time monitoring through the use of a programmable interrupt. Also, the device includes a PRBS frame generation tool, which is completely compatible with internal loopbacks, to transmit and receive data with no need for the use of a MAC. The DP83TC811R-Q1 is housed in a 6mm × 6mm, 36-pin VQFN wettable flank package.
