Pushing the Limits of High-Speed Connectivity with Chiplet-Ready IP and Next-Gen DSPs

Alphawave Semi is accelerating the evolution of high-performance data infrastructure with a new wave of connectivity solutions engineered for AI, compute, and networking systems. From ultra-fast SerDes to chiplet-compatible die-to-die IP, their latest technologies are built for a future of modular, scalable architectures.

224G PAM4 SerDes: Unlocking the Next Generation

At the forefront is Alphawave Semi’s 224G PAM4 Electrical SerDes, a next-generation XLR IP subsystem that supports blazing-fast data rates. This solution is designed to meet the growing demand for high-bandwidth interconnects in data centers and advanced AI platforms, delivering both speed and power efficiency.

1.6T Multi-Standard I/O Chiplets

Their 1.6T I/O chiplet solutions are silicon-ready and enable scalable integration of PCIe and Ethernet interfaces across system designs. These chiplets are optimized for multi-vendor interoperability and deliver the flexibility needed for heterogeneous integration in modern architectures.

UCIe D2D IP: Ready for Optical Chiplets

Alphawave Semi is also leading in UCIe (Universal Chiplet Interconnect Express) development. Their Gen3 UCIe IP enables ultra-high-speed die-to-die connectivity at 64 Gbps per lane with over 20 Tbps/mm of bandwidth density, all while maintaining ultra-low power and latency. This technology supports both advanced packaging and standard organic substrates, and is tailored for the rise of optical chiplet architectures.

Optical PCIe and Long-Reach Interconnects

To support systems requiring longer reach, Alphawave Semi offers solutions that extend high-speed optical and electrical connections up to 20 kilometers. Their Optical PCIe Subsystem ensures robust signal integrity across long-haul links, enhancing data throughput in high-performance environments.

Advanced DSP Architectures for Modern Links

The company has introduced a trio of specialized DSPs for various link types:

• Cu-Wave™ PAM4 DSP: Designed for Active Electrical Cables (AEC), supporting cost-effective, high-speed connections in dense environments.

• O-Wave™ PAM4 DSP: Tailored for optical retimer and gearbox transceivers, offering improved signal fidelity and energy efficiency.

• Co-Wave™ Coherent-Lite DSP: A high-performance solution for optical transceivers that need lower power coherent communication.

These DSPs are underpinned by Alphawave’s proprietary WidEye™ architecture and EyeQ™ diagnostics, providing advanced monitoring, tuning, and performance optimization.

Built for the Future of Modular Compute

As data workloads grow and systems scale, Alphawave Semi’s technologies are laying the groundwork for the next generation of chiplet-based architectures. Their IP and silicon offerings are enabling industry leaders to build systems that are faster, more flexible, and ready for the future of AI and high-speed compute.
