(NASDAQ: MRVL), a leader in data infrastructure semiconductor solutions, has delivered two optical PAM4 digital signal processors (optical DSPs) to enable cloud operators to serve the exploding demand for AI, accelerated computing and cloud services by optimizing the performance, bandwidth and efficiency of the optical links connecting data infrastructure.\nSampling to select customers now, Perseus is the industry's first 400/800 Gbps 5nm device that monolithically integrates the primary electrical components of a short-reach pluggable optical module — an optical DSP, a transimpedance amplifier (TIA) and a vertical-cavity surface-emitting laser (VCSEL) driver — into a single die to reduce power, space and cost. Monolithically integrating components also reduces manufacturing complexity for module manufacturers to enable them to scale faster. Perseus is also available with an integrated silicon photonics driver.\nPerseus is optimized for both active optical cables (AOCs), which replace passive copper cables for connecting equipment within racks, and short-reach single mode and multi-mode optical interconnects for distances of five to 500 meters.\nMeanwhile, the Marvell® Spica Gen2, which began sampling in late 2022 and is now in volume production, is an 800 Gbps 5nm optical DSP optimized for longer-reach connections such as the high-bandwidth optical connections linking servers within an AI cluster or the optical connections between racks in a hyperscale data center. Spica Gen2 enables pluggable optical module manufacturers to reduce the power consumption of products to below 12 watts, a 25% savings over the previous generation of devices.1\nBoth chips are the latest products in a growing portfolio of optical and copper connectivity chips from Marvell optimized for specific use cases to help cloud operators maximize the...
