The PLDA PCI Express (PCIe) 6.0 Controller (formerly XpressRICH) is configurable and scalable controller IP designed for ASIC implementation. The controller supports the PCIe 6.0 specification, including 64 GT/s data rates, PAM4 signaling, FLIT mode, and L0p power state. The PCIe 6.0 architecture will be essential for SoC designers creating next-generation chips that require the movement of large amounts of data within systems, including applications like HPC, cloud computing, artificial intelligence/machine learning (AI/ML), enterprise storage, networking, and automotive.
