UCIe PHY on Samsung SF5A

Overview

Synopsys UCIe PHY IP enables high-bandwidth, low-power and low-latency die-to-die connectivity in a package for hyperscale data centers, AI, and networking applications. The PHY’s flexible architecture supports standard and advanced package technologies and delivers up to 4Tbps bandwidth in a multi-module configuration. Supporting widely used protocols such as PCI Express and CXL and enabling latency-optimized NoC-to-NoC links with streaming protocols, the IP offers maximum performance, minimum latency and implementation flexibility. Synopsys UCIe PHY IP delivers high energy efficiency with an optimized architecture that uses clock forwarding and low-voltage signaling. The IP implements a comprehensive set of testability features to ensure known good dies and offers test and repair capabilities to improve package assembly yield. Robust die-to-die link operation is ensured with embedded training and calibration algorithms. Synopsys UCIe PHY IP interoperates with Synopsys UCIe Controller IP to deliver a complete, low-latency solution for die-to-die links in any package.
