Texas Instruments DP83TG720S-Q1 Automotive Ethernet PHY

Texas Instruments DP83TG720S-Q1 Automotive Ethernet PHY is an IEEE 802.3bp and Open Alliance compliant automotive Ethernet physical layer transceiver. The device provides all of the physical layer functions needed to transmit and receive data over unshielded/shielded single twisted-pair cables. The device provides xMII flexibility with support for RGMII and SGMII MAC interfaces.

Texas Instruments DP83TG720S-Q1 is compliant with Open Alliance EMC and interoperable specifications over unshielded twisted cable. DP83TG720S-Q1 is pin-2-pin compatible with TI’s 100Base-T1 PHY enabling design scalability with a single board for both speeds. This device offers the Diagnostic Tool Kit, with 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. It 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 DP83TG720S-Q1 includes a data generator and checker tool to generate customizable MAC packets and check the errors on incoming packets. This feature enables system-level datapath tests/optimizations without dependency on MAC.
