Overview

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.

Features
  • 100Base-T1 and 1000Base-T1 automotive Ethernet connection through RGMII to Jacinto™ 7 processors
  • Option to provide the same clock to all four Ethernet PHYs option to populate TI's BAW oscillator
  • Automotive qualified filter network for 12V power coupling
  • Board ID EEPROM for identification
