This reference design interfaces with Jacinto™ 7 processor EVM boards through the RGMII Ethernet Expansion Connector. Four automotive Ethernet connections are added through TI's automotive Ethernet physical layers (PHY). This design shows an implementation with TI's DP83TC818S-Q1 100Mbps and DP83TG721S-Q1 1000Mbps single-pair Ethernet (SPE) PHY. A coupling network is used to couple in 12V to the data line.
A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
