Enables 1.6T short-reach copper connectivity within accelerated compute racks.SANTA CLARA, Calif., June 27, 2024 /PRNewswire/ -- Marvell Technology, Inc. (NASDAQ: MRVL), a leader in data infrastructure semiconductor solutions, today introduced the Marvell® Alaska® A 1.6T PAM4 DSP for active electrical cables (AECs), the industry's first 1.6 Tbps AEC DSP to address emerging 200G/lane-based accelerated infrastructure architectures. Artificial intelligence (AI) and machine learning (ML) applications are driving greater connectivity bandwidth requirements between AI accelerators, server to top-of-rack links and switch-to-switch interconnects within data center racks. The latest addition to the Alaska A family is built on 5nm process and leverages industry-leading Marvell PAM4 DSP technology to enable short-reach copper interconnect solutions that meet the growing bandwidth requirements of accelerated infrastructure.\nAccording to 650 Group, the AEC silicon market is expected to grow at 64% per year to reach $1 billion by 2028 with DSPs powering AECs to reach nearly 40 million units per year1. \"AI is driving the need for short-reach copper connectivity at 1.6T,\" said Alan Weckel, 650 co-founder. \"Marvell leadership is clear with the introduction of its Alaska 1.6T AEC DSP, which continues the company's history of delivering best-in-class PAM DSPs that enable cable vendors to offer interconnect solutions optimized for the different cloud AI architectures.\"\nCopper PAM4 DSP Technology for Accelerated InfrastructureThe short-reach copper connections between AI accelerators, server to top-of-rack links and switch-to-switch interconnects within a rack have traditionally been addressed by direct attached cable (DAC). As speeds increase to 200G/lane, the distance over which passive DACs can be used declines significantly. AECs use PAM4 DSPs to retime the signal to extend the reach of copper interconnects and enable thinner cables within high-density data center racks.\nAECs are increasingly being used in a wide variety of applications, including as part of the AI server compute fabric. Historically, most AI server designs used copper...
