• Product Introduction
D2D(UCIe 1.1)


The Die-to-Die interface is a functional block that provides a data interface between two chip dies within the same package. MSquare's M2LINK D2D Solution compatible with UCIe v1.1 specification contains Die-to-Die adapter layer and physical layer, each layer contains a sideband interface to provide a back-channel for link training and access of registers of the link partner,  as shown in Figure 1. This Unique hybrid analog/digital architecture offers low power, compact area and robust performance, making it well-suited for target applications such as High-performance Computing、AI or Multimedia SoC and Die-to-Die interconnection etc.
