Credo's Cardinal 1.6T optical DSP family addresses the bandwidth, scale, and power requirements of massive AI clusters with a proven low‑power architecture, superior latency with the flexibility to support both retimed 1.6T optics, and ultra‑efficient linear‑receive implementations.

News Highlights:

• Credo has announced its second generation of 1.6T optical DSP family for addressing the bandwidth, scale, and power requirements of massive AI clusters.
• The Cardinal family of devices includes low-power, high-swing integrated EML and silicon photonics drivers.
• The Cardinal family consists of dedicated DSPs for full-retimed and linear receive optics (LRO) applications.

AI compute clusters are pushing the limits of network infrastructure, with high‑radix switches, dense GPU topologies, and massive east‑west traffic patterns. These environments demand optics that deliver maximum bandwidth per watt, extremely low bit error rates, and robust monitoring for uptime and serviceability. Cardinal delivers on each of these fronts enabling 1.6T transceivers with a comprehensive link monitoring toolkit while consuming less than 15W in LRO implementations.

“AI fabrics have shifted the center of gravity for optical design, and Cardinal was developed from day one with those unique requirements in mind,” said Chris Collins, AVP of Sales & Optical Product Marketing at Credo. “By combining a proven low‑power architecture, superior latency with the flexibility to support both retimed 1.6T optics, and ultra‑efficient linear‑receive implementations, Cardinal gives our customers the exact tools they need to scale their AI infrastructure.”

“Credo’s LRO solution in the Cardinal family will be a critical enabler for our teams to deliver ultra-low power optical solutions designed for rack-scale AI infrastructure,” said Jason Wildt, VP/GM, Photonics at Jabil, a global engineering, supply chain, and manufacturing solutions provider. “The power savings and associated thermal benefits are exactly what is needed for high‑density GPU clusters. Cardinal’s LRO option will provide our customers a solution that allows them to pack more performance into their power footprint.”
