224G SerDes PHY and controller for UALink for AI systems

Overview

Efficient Scaling of AI Accelerators for Achieving High Performance and Throughput

UALink, the standard for AI accelerator interconnects, facilitates this scalability by providing low-latency, high-bandwidth communication. As a member of the UALink Consortium, Cadence offers verified UALink IP subsystems, including controllers and silicon-proven PHYs, optimized for robust performance in both short and long-reach applications and delivering industry-leading power, performance, and area (PPA).

Key Features

Unmatched Bandwidth, Ultra-Low Latency, and Power Efficiency for AI Accelerators

  • XPU-to-XPU Scale-Up Connectivity — The UALink subsystem IP enables scale-up connectivity for AI systems, supporting the emerging 1.6T and 800G networks
