Single-pair Ethernet PHY

Simplify your designs. Long reach IEEE 802.3cg (10BASE-T1L) PHYs provide cable reuse in existing system. Robust EMC/EMI, AEC-Q100 footprint compatible portfolio enables flexible design in vehicles.

Standard Ethernet PHY

Design deterministic and low latency networks using our standard Ethernet PHYs with two or four twisted pairs of wires. High immunity, low emissions PHYs offer various temperature and package options.
