Time Sensitive Networking (TSN) is bouquet of IEEE standards defined to converge the various priority traffic on the same network. Most of the standards have implications on MAC however these standards have two requirements on Ethernet PHYs.
1. TSN IET specifications ( 802.1Qbr and 802.1Qbu) defines new SMD type for Ethernet Frame.
2. Low and deterministic latency.
Texas Instruments 100Base-Tx, 1000Base-T, 10Base-T1L, 100Base-T1 and 1000Base-T1 supports both above requirements and are TSN compliant.
