KeystoneMM, a PAM4 DSP from MaxLinear, integrates VCSEL drivers for 800G and 400G multimode short-reach optical modules and energetic optical cables. The 5-nm CMOS system reduces each energy consumption and price for energetic optical cables (AOCs) and multimode hyperlinks utilized in information facilities and AI/ML clusters.
The corporate stories that multimode optical hyperlinks are extra economical than single-mode optical options for short-reach purposes. These shorter-reach hyperlinks dominate the interconnect quantity for many AI/ML deployments. Drew Guckenberger, vp of Excessive Velocity Interconnect at MaxLinear, commented, “Our 5-nm Keystone PAM4 DSP with built-in VCSEL drivers addresses the calls for of this key market, enabling best-in-class energy consumption of <10 W for 800G short-reach optical transceivers and AOCs.”
KeystoneMM, half quantity MxL93684, is the most recent member of the Keystone 5-nm PAM4 DSP household. Supposed for each 400G and 800G purposes, the collection gives 106.25-Gbps host-side electrical I/O to match the line-side 106.25-Gbps interface fee. Variants help single-mode optics (EML and SiPh), multimode optics (VCSEL transceivers and AOCs), and energetic electrical cables (AECs). As well as, they are often paired with the corporate’s companion transimpedance amplifiers (TIAs).
KeystoneMM is accessible to pattern to key clients and shall be launched to full manufacturing in Q1 2024. A datasheet for the system was not out there on the time of this announcement. Click on right here to for extra details about MaxLinear’s portfolio of PAM4 DSPs.
