Credo Technology Group Holding Ltd announced the Cardinal series optical DSP, a 3nm-based, low-power, highly integrated product with 224G single-channel rate intended for AI computing architectures.

Credo Technology Group Holding Ltd (Credo) (NASDAQ: CRDO), an innovative company driving the transformation of large-scale connectivity by providing fast, reliable, and energy-efficient system solutions, recently announced the Cardinal series of optical DSPs. Based on a 3nm process, these low-power, highly integrated products offer 224G bandwidth per channel and are designed to meet the explosive demands of modern AI computing architectures for bandwidth, latency, and reliability.

News Highlights

Credo announced the launch of its second-generation 1.6T optical DSP series, designed to meet the stringent bandwidth, scale, and power consumption requirements of large-scale AI clusters.

Cardinal series products incorporate low-power, high-swing EML and silicon photonic drivers.

The Cardinal product line includes dedicated DSPs specifically designed for full-retimed applications and linear receiver optical modules (LRO) applications.

AI computing clusters are constantly pushing the limits of network infrastructure, as evidenced by high-cardinality switches, dense GPU topologies, and massive east-west traffic patterns. These environments place extremely high demands on optical interconnects: they must provide maximum bandwidth per watt, extremely low bit error rates, and robust monitoring capabilities to ensure uptime and maintainability. Cardinal addresses these key performance indicators, delivering 1.6T transceivers with power consumption below 15W (in LRO applications), while also providing a comprehensive link monitoring toolkit to ensure stable operation and serviceability in large-scale AI clusters.

Chris Collins, Vice President of Sales and Optical Product Marketing at Credo, stated, "AI network architecture has shifted the focus of optical interconnect design, and the Cardinal series has been built around these unique needs from the outset. By combining a proven low-power architecture, superior low-latency performance, and the flexibility to support both full-timing 1.6T optical modules and ultra-efficient linear receiver solutions, Cardinal provides our customers with the ideal solution for scaling their AI infrastructure."

Jason Wildt, Vice President and General Manager of the Optical Business Unit at Jabil, a global provider of engineering, supply chain, and manufacturing solutions, stated, "The LRO solution in the Credo Cardinal series will be a key driver for our team to deliver ultra-low-power optical interconnect solutions designed specifically for rack-mount AI infrastructure. Its energy-saving benefits and corresponding thermal advantages are exactly what high-density GPU clusters urgently need. Cardinal's LRO option provides customers with a platform that can unleash greater computing power with limited energy consumption."
