4 Summary

This application note serves as a guide to help determine if an Ethernet PHY is compliant with PROFINET's system requirements. Furthermore, this application note provides examples of Ethernet PHYs currently offered by Texas Instruments and how to configure them. These has low latency Ethernet PHYs that meet the requirements needed for use in a PROFINET system and have the ability to be configured through hardware bootstraps or software register writes.
