New META-DX2C 800G retimer is supported by a complete hardware and software reference design with key Microchip components
Nov. 9, 2023 — The rise of generative AI and AI/ML technologies is fueling demand for more high-speed connections and, in turn, the push toward 800G connectivity in backend data center networks and applications.This can be optimally addressed using Active Electrical Cables (AECs), but there are numerous design and development hurdles for cable vendors to overcome. To address this, Microchip Technology Inc. (Nasdaq: MCHP) today announces an accelerated development path for these Quad Small Form Factor Pluggable Double Density (QSFP-DD) and Octal Small Form Factor Pluggable (OSFP)AEC cable products using its META-DX2C 800G retimer. The retimer is supported by a comprehensive solution for 800G AEC product development including a hardware reference design and complete Common Management Interface Specification (CMIS) software package to minimize development resources needed for cable manufacturers.
“The newest and most compact member of our META-DX2 Ethernet PHY family leverages Microchip’s unique breadth of microcontrollers and other key components to provide a complete reference design thataccelerates AEC product development, reduces resource investments and simplifies supply-chain management,” said Maher Fahmi, vice president for Microchip’s communications business unit.“The META-DX2C retimer enables AEC connections for the high-density networksthat are needed for generative AI applications.”
The META-DX2C retimer useshigh-performance, long-reach 112G SerDes that can support up to 40dB reach, enabling the design of thinner and longer AECsthat are crucialfordense hyperscaler infrastructure buildouts. Additionally, Microchip is offering a fully validated paddle card hardware reference design and a software package that implements the CMIS software in a Microchip 32-bit PIC32 microcontroller.Microchip’s META-DX2C compact retimer can also solve similar connectivity challenges in high-capacity datacenter switches and routers where high density and data rates create signalintegrity problems.
“Generative AI is impacting how data center infrastructure is being built and the amount of network connectivity that is required, in a big way,” said Alan Weckel, co-founder and analyst with the market research firm 650 Group. “To address this challenge, hyperscalers need solutions that are very high bandwidth as well as low power and low cost. We are seeing a transition to active electrical cables as the optimal solution for this challenge. Microchip’s META-DX2C 800G AEC retimer is aligned with this trend and is the type of solution needed to enable growth in this area.”
Development Package
Microchip’s META-DX2C 800G AEC solution is supported by a paddle card reference design that includes the META-DX2C retimer, PIC32 microcontroller, oscillators, buck regulator and linear voltage regulator, all from Microchip. Having these elements available from a single supplier can simplify a customer’s supply chain management. The included software development kit supports the CMIS 5.2 specification.
