Texas Instruments DP83TC811R-Q1 Automotive Ethernet Transceivers

Texas Instruments DP83TC811R-Q1 Low-Power Auto PHYTER™ 100BASE-T1 Automotive Ethernet Transceivers present all physical layer functions necessary to transmit and receive data over unshielded single twisted-pair cables. The DP83TC811R-Q1 supports MII, RMII, and RGMII MAC interfaces offering xMII flexibility. The included Diagnostic Tool Kit provides an extensive list of real-time monitoring tools, debug tools, and test modes. Additionally, the kit consists of an electrostatic discharge (ESD) monitoring tool capable of counting ESD events on both the xMII and MDI.

The ESD monitoring tool also applies a programmable interrupt providing real-time monitoring. The pseudo-random binary sequence (PRBS) frame generation tool transmits and receives data without using a MAC and is fully compatible with internal loopbacks. The Texas Instruments DP83TC811R-Q1 is available in a 6mm×6mm, 36-pin VQFN wettable flank package.
