The newly launched connectivity products, currently available for sampling, include:

• Cu-Wave PAM4 DSP – for Active Electrical Cables (AEC)
• O-Wave PAM4 DSP – for Optical Retimer and Gearbox Transceivers
• Co-Wave Coherent-lite DSP – for Optical Transceivers

Babak Samimi, SVP & GM, Connectivity Products Group, Alphawave Semi:“The industry is shifting with AI-driven data center campuses redefining compute infrastructure. To address this, we have advanced our PAM4 innovations and pioneered Coherent-lite DSPs, reinforcing our commitment to becoming a trusted supplier in the high-speed optoelectronics semiconductor market. Our team has harnessed high-speed SerDes, precision analog, SoC expertise, signal integrity management, and our proprietary WidEye and EyeQ™ technologies to support this transformation. Collaborating with a leading North American hyperscaler and key ecosystem partners, we look forward to deploying these solutions over the next year.”

Vladimir Kozlov, CEO, LightCounting:“With a strong foundation in high-speed SerDes and leading-edge process nodes, Alphawave’s market entry is poised to be highly disruptive. As distributed processing expands across data center campuses, the demand for PAM4 and Coherent-lite DSPs will grow, with the market expected to exceed $4 billion by 2028. Alphawave’s capability to provide both technologies positions it as a key player in this evolution.”

Tony Pialis, CEO, Alphawave Semi:“The launch of the Connectivity Products Group marks a strategic milestone, enabling us to serve hyperscalers in multiple ways—whether through IP subsystems, custom silicon, or off-the-shelf connectivity products. This reinforces our mission to be a semiconductor leader in AI connectivity and compute.”
