PCIe 6.1 Controller

The PCI Express® (PCIe®) 6.1 Controller is configurable and scalable controller IP designed for ASIC implementation. The controller supports the PCIe 6.1 specification, including 64 GT/s data rates, PAM4 signaling, FLIT mode, and L0p power state. The PCIe 6.1 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.

How the PCIe 6.1 Controller Works

The PCIe 6.1 controller is backward compatible to the PCIe 5.0, 4.0 and 3.1/3.0 specifications. It supports version 6.x of the PHY Interface for PCI Express (PIPE) specification. The controller exposes a highly efficient transmit (Tx) and receive (Rx) interface with configurable bus widths. Designed to satisfy a multitude of customer and industry use cases, the IP can be configured to support endpoint, root port, switch port, and dual-mode topologies, allowing for a variety of use models. The provided Graphical User Interface (GUI) Wizard allows designers to tailor the IP to their exact requirements, by enabling, disabling, and adjusting a vast array of parameters.

The PCI Express® (PCIe®) interface is the critical backbone that moves data at high bandwidth and low latency between various compute nodes such as CPUs, GPUs, FPGAs, and workload-specific accelerators. With the rapid rise in bandwidth demands of advanced workloads such as AI/ML training, PCIe 6.1 jumps signaling to 64 GT/s with some of the biggest changes yet in the standard.
