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. 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 a complete Common Management Interface Specification (CMIS) software package to minimize development resources needed for cable manufacturers.
The META-DX2C retimer uses high-performance, long-reach 112G SerDes that can support up to 40 dB reach, enabling the design of thinner and longer AECs that are crucial for dense 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 data center switches and routers where high density and data rates create signal integrity problems.
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.
The META-DX2C retimer, part #PM6254, with the hardware reference design, firmware solution, and SDK, is available now. For additional information visit the META-DX family webpage or contact a Microchip sales representative.
