Microchip - META-DX1 family of Ethernet Physical-Layer (PHY) devices



Industry’s First Terabit-Scale Ethernet PHY Enables Highest-Density 400 GbE and FlexE Connectivity. META-DX1 uniquely combines 100 GbE, 400 GbE, FlexE, nanosecond timestamping accuracy and MACsec security engine in a single chip with terabit capacity.

META-DX1 family of Ethernet Physical-Layer (PHY) devices that integrates, onto a single chip, Ethernet ports from 1 Gigabit Ethernet (GbE) to 400 GbE, flexible Ethernet (FlexE), Media Access Control Security (MACsec) link encryption and nanosecond timestamping accuracy at terabit capacity. The META-DX1 enables line cards to quadruple in capacity – from 3.6 terabits per second (Tbps) to 14.4 Tbps with 36 ports of 400 GbE or 144 ports of 100 GbE – while supporting key features needed by service providers.
