100BASE-T1 Ethernet PHY

MegaChips is the only Japanese manufacturer to have developed a 100BASE-T1 compliant 100Mbps Ethernet PHY. This is ideal for the products that require space saving and reduced wiring in robot and industrial devices.


  1. 100BASE-T1 compliant Ethernet PHY
    100Mbps full-duplex communication with a pair of UTP cables. High-speed communication is available with a lightweight and lower-cost wire harness.

  2. Reduced wiring/space saving
    Unlike 100BASE-TX, 1-Pair (no shield required) wiring and an external transformer is not required, thus achieving a reduction of wires and the saving of space.

  3. Compliant with automotive quality standards AEC-Q100
    We guarantee quality in conformity with automotive quality standards.
