“With the exponential growth of data traffic within hyperscale cloud networks, the needed increase in interconnect bandwidth in those networks requires a range of lower-power, higher-density interconnect solutions that support the required higher data rates”

An ongoing surge in the use of cloud services to increase productivity and improve customer experiences underlies the growth of hyperscale data centers. According to Precedence Research, the global hyperscale data center market size is projected to reach approximately US$593B by 2030, up from an estimated US$62B in 2021. This massive increase in scale comes at an ever-increasing cost. Climate control measures are often more expensive, operationally, than running the compute. Further, heat removal systems usually have a large, detrimental carbon footprint. Low-power solutions are absolutely critical for these applications.

“With the exponential growth of data traffic within hyperscale cloud networks, the needed increase in interconnect bandwidth in those networks requires a range of lower-power, higher-density interconnect solutions that support the required higher data rates,” said Drew Guckenberger, Vice President of High-Speed Interconnect at MaxLinear. “The extremely low power consumption and small form factors of Keystone solutions enable both 7Watt 400G optical module designs and 13Watt 800G designs. Significantly, we are now also extending these power advantages to the Active Electrical Cable (AEC) market, providing best-in-class power consumption there as well. With the power advantages of 5nm CMOS technology, we are directly addressing our customers’ critical needs for low power, highly integrated, high performance interconnect solutions in next generation hyperscale cloud networks.”

The Keystone 5nm DSP family has been designed to address both 400G and 800G applications. Variants supporting single mode optics (EML and SiPh), multimode optics (VCSEL transceivers and AOCs) and Active Electrical Cables (AECs) are all available and can be paired with companion TIAs to provide complete solutions for our customers.

The Keystone family will be on display during the OFC Conference from March 7 – 9, 2023, booth 2207. Contact MaxLinear to schedule a briefing.
