2024年12月19日 · Within PCIe, two key components — PHY (Physical Layer) and MAC (Media Access Control) — play a critical role in ensuring efficient and reliable communication. This article provides a...

For PCIe 5.0, 6.0, and beyond, please see PHY for PCIe and CXL. Single macro supports max 16Gbps with up to 16 lanes for long-reach applications. Compliance proven, customer SoCs in volume production. Fully validated by Cadence’s rigorous IP …

The Physical Layer is the lowest level of the PCI Express protocol stack. It is the layer closest to the serial link. It encodes and transmits packets across a link and accepts and decodes received packets.

Most advanced PHY and controller IP for HPC, AI/ML, data communications, networking, and storage systems. Cadence ® PHY IP for PCI Express ® (PCIe ®) 6.0 is a high-performance NRZ/PAM4 SerDes designed specifically for infrastructure and data center applications.

The PHY Interface for the PCI Express Architecture (PIPE) is intended to enable the development of functionally equivalent PCI Express PHY's. Such PHY's can be delivered as discrete IC's or as macrocells for inclusion in ASIC designs.

This purpose of this functional separation is to allow ASIC and integrated circuit designers to focus on the PCI Express device core, Transaction, Data Link and logical Physical Layers, while relying on the PIPE-compliant physical design (PHY) for the electrical interface of the design.

The PCI Express PHY Layer handles the low level PCI Express protocol and signaling. This includes features such as analog buffers, receiver detection, data serialization and de-serialization, 8b/10b encoding/decoding, 128b/130b encoding/decoding (8 GT/s, 16 GT/s, 32 GT/s), and elastic buffers.

The PHY Interface for the PCI Express*, SATA*, and USB* Architectures (PIPE) is intended to enable the development of functionally equivalent PCI Express, SATA and USB PHY's. Such PHY's can be delivered as discrete IC's or as macrocells for inclusion in ASIC designs.

2022年12月15日 · This article covers the steps required to succesfully instantiate the Phyical Layer (Gen 1 or Gen 2) of a PCIe Transceiver, including the PHY Interface for PCI Express (PIPE), on a Stratix V FPGA (For Quartus II v11.0 or v12.0sp2).

The Lattice PCS PIPE IP core offers PCI Express PHY device functionality, compliant to the Intel PIPE Architecture Draft Version 1.00 (PIPE Ver 1.00), to any endpoint solutions. The PCS PIPE IP core utilizes the SERDES/PCS integrated in LatticeECP3 and LatticeECP2M FPGAs.
