Marvell Announces Availability of Active Power Cables Powered by Its Cutting-Edge PAM4 DSP Technology

Leading Cable Manufacturers Offer Cloud-Optimized Interconnects to meet the growing demand for data center bandwidth

SANTA CLARA, Calif., October 20, 2022 /PRNewswire/ — Marvell Technology, Inc. (NASDAQ: MRVL), a leader in semiconductor solutions for data infrastructure, today announced that leading cable manufacturers are sampling for data center operators cloud their 100G/lane Active Electrical Cables (AEC) powered by Marvell® Alaska® A PAM4 DSP. At these speeds, the physical reach that can be achieved with passive direct-attach (DAC) cables is less than the distance requirements for server-ToR (top-of-rack) and switch-to-switch interconnects. In order for cloud operators to continue to double their data center bandwidth, most of these interconnects need to switch from DAC to AEC. The Alaska A PAM4 DSP family enables cable manufacturers to deliver optimized AEC solutions that meet the unique and diverse requirements of leading cloud data center operators. The emerging category of AEC interconnect products expands Marvell’s addressable market for high-speed DSP technology.

New AECs enable next-generation 400G, 800G, and 1.6T server-to-switch and switch-to-switch interconnects that require 100G serial I/O for data-intensive artificial intelligence, machine learning, and high computing workloads performance. Marvell’s PAM4 SerDes technology and IP Ethernet in the Alaska A family underpin the performance of the new interconnects, complemented by the power and speed advantages of an edge process node.

Marvell’s Alaska A family further applies advanced DSP equalization techniques and flexible firmware-based implementation to optimally compensate for cable-introduced impairments on the high-speed 100G PAM4 signal. This enables the deployment of thin cables that meet the reach and flexibility needs of next-generation data center architectures.

“Alaska A DSPs are the foundation of 100G/lane serial connectivity and have extended Marvell’s PAM4 DSP portfolio to short-range interconnects in cloud data centers,” said Venu Balasubramonian, vice president of product marketing, broadband connectivity and the PHY business unit at Marvell. “The availability of these high-performance AECs from major cable vendors is an important step in solving the 100G/lane architectures that are set to be the next inflection point for data centers.”

“Amphenol’s AEC interconnect products incorporating Marvell’s Alaska A DSPs enable us to deliver an advanced solution with the performance needed for next-generation infrastructure architectures,” said Brian Kirk, CTO at Amphenol. “Delivering these AEC interconnects to our customers underscores the critical performance and reliability requirements they meet for 100G/lane connectivity.

“Our data center customers are looking to extend the range of links at higher data rates as speeds continue to increase and cable functionality continues to become increasingly important for cloud infrastructure,” said Brian Hauge, vice president and general manager, Copper Solutions, Molex. “Our latest AEC portfolio bundled with Marvell’s Alaska A DSPs provides a compelling solution to our customers for their high performance interconnect architectures.”

“Next-generation data centers with 100G/lane Ethernet will require advanced cabling solutions to meet reach, flexibility and power requirements,” said mike tryson, CTO and Vice President of Engineering at TE Connectivity. “Combining Marvell’s Alaska A DSP with TE’s advanced 100G cabling capability will enable a portfolio of AEC solutions for critical data center applications.”

“A data center is only as strong as its weakest link. We expect AEC adoption to happen rapidly with shipments of AEC chips increasing 10-fold to nearly 25 million units per year by 2026,” said Alain Weckelco-founder of the 650 Group. “AEC cables will play a pivotal role in top-of-rack server switching in the data center as server speeds increase to 100 Gbps and beyond. based on AI/ML are already pushing the limits of current cable technology.”


Active Power Cables Powered by Marvell Alaska A PAM4 DSPs are now sampling at Amphenol, Molex and TE Connectivity.
