Microchip Unveils Terabit-Scale Ethernet PHY Devices

Microchip Technology, via its Microsemi subsidiary, is the first to enabling cloud and telecom service providers with routing and switching platforms with its 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.

As a study by Cisco predicted that data center to data center traffic to grow at more than a 30 % CAGR, 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.

The META-DX1 MACsec engine secures traffic leaving the data center or enterprise premises, and FlexE enables both cloud and telecom service providers to meet capacity requirements while reducing fiber plant capital expenditures by optimally configuring links beyond today’s fixed-rate Ethernet so they can use low-cost high-volume optics.

The device uniquely combines MACsec and FlexE into one solution to meet the next phase of capacity scaling in data center interconnect (DCI) buildouts. Its integrated flexible crosspoint switching capability makes it easier for OEMs to navigate the market transition from 25 Gbps NRZ and 56 Gbps PAM-based architectures by enabling them to support a single design or SKU for both 100 GbE (QSFP28) and 400 GbE (QSFP-DD) optics. By providing high-performance timestamping with nanosecond-level accuracy on every port, META-DX1 also ensures network buildouts will meet the challenging timing requirements of 5G mobile base station deployments.

“The META-DX1 family was purpose-built to unify into single hardware and software offering the broad range of capabilities service providers need in their network buildouts that connect enterprise and data center services to the cloud and emerging 5G applications,” said Babak Samimi, vice president for Microchip’s Communications business unit.

Product Availability

Initial META-DX1 family members will sample during the third calendar quarter of 2019. All are hardware-compatible and supported by the same Software Developer’s Kit (SDK).
