Following its acquisition of Inphi, Marvell has launched three new products for cloud data centres. The Atlas™ 50Gbps PAM4 DSP chipset solution (pictured) for high-performance cloud data centre, computing and emerging AI applications, extends Marvell’s networking portfolio and its addressable market. The company also introduced what it claims is the industry’s first 1.6T Ethernet PHY with 100G PAM4 electrical input/outputs (I/Os) in 5nm. Marvell also expanded its Coherent Digital Signal Processor (CDSP) portfolio with the new Deneb™ ultra-low power, multi-mode 400G DSP. The new products are part of Marvell’s stated aim to “develop and deliver semiconductor solutions that move, store, process and secure the world’s data faster and more reliably than anyone else.”
The Atlas chipset, based on Marvell’s market-leading Polaris™ 50G PAM4 DSP family, is the industry’s first PAM4 DSP solution to integrate transimpedance amplifiers (TIAs) and laser drivers in mainstream CMOS technology, reducing supply chain complexity and power consumption by up to 25%. Atlas is also the industry’s first PAM4 DSP available to wire bond directly with lasers and photodiodes, further simplifying the assembly process for optical module integrators, effectively reducing both product lead times and time to market.
“Disaggregated data centres define today’s new cloud computing paradigm, and this trend is driving hyper-connectivity within the data centre, putting PAM4 data centre interconnects at the heart of the network,” said Xi Wang, VP of Marketing, Optical Connectivity at Marvell. “The new Atlas PAM4 DSP targets this burgeoning, high-volume data centre market as well as cost-sensitive applications at the network edge.”
The 1.6T Ethernet PHY features 100G PAM4 electrical input/outputs (I/Os) in 5nm. The demand for increased bandwidth in the data centre to support massive data growth is driving the transition to 1.6T (Terabits per second) in the Ethernet backbone. 100G serial I/Os play a critical role in the cloud infrastructure to help move data across compute, networking and storage in a power-efficient manner. The Marvell® Alaska® C PHY is designed to accelerate the transition to 100G serial interconnects and doubles the bandwidth speeds of the previous generation of PHYs to bring scalability for performance-critical cloud workloads and applications such as artificial intelligence and machine learning.
“100G serial electrical signalling is vitally important because it serves as the foundational speed for the next generation of high-speed networks,” said Alan Weckel, founder and technology analyst of 650 Group. “Challenges in signal integrity typically arise as I/O speeds increase. As the industry transitions to 100G serial electrical signalling on high density switches and optics, Marvell’s 1.6T PHY is the only solution that’s available in the market today to support this transition.”
Marvell also extended its Coherent Digital Signal Processor (CDSP) portfolio with the new Deneb™ ultra-low power, multi-mode 400G DSP. Driving the largest open CDSP ecosystem in the world, Deneb enables the advancement of disaggregated optical architectures for global operators and accelerates the adoption of IP-over-DWDM (IPoDWDM) for optimal data centre interconnects (DCIs). Compatible to its predecessor, Canopus™, the industry’s first 7nm CDSP for 400G pluggables, Deneb offers customers a seamless upgrade to interoperable pluggables across multiple platforms. Introduced from the recent Inphi acquisition, the CDSP technology extends Marvell’s industry leading networking portfolio for hyperscale cloud data centres and 5G carrier infrastructure.
“The right technology is in place for coherent pluggable optics to take off. Deneb extends the market addressed by Canopus for Marvell and its partners, makes standards-based interoperability a reality, and will propel growth in pluggable coherent-enabled networks,” said Andrew Schmitt, Directing Analyst at Cignal AI. “Network operators have the tools and the desire to move forward, and we anticipate that the coherent pluggable optics market will triple year over year between now and 2022.”
