PCIe 7.0 PHY IP

Overview

The multi-channel PHY IP for PCI Express® (PCIe®) 7.0 meets today’s demands for higher bandwidth and power efficiency across backplane, and chip-to-chip channels. The PHY’s unique DSP algorithms optimize receiver equalization and the patent-pending diagnostics features enable near zero link downtime. The PHY minimizes package crosstalk, allows dense SoC integration for x16 links, and achieves ultra-low-latency with an optimized data path that is based on an ADC architecture. Support for multiple standards form factors including OCP 3.0, U.2, and U.3 enables serve and storage applications.

The PHY IP for PCIe 7.0, available in advanced FinFET processes including 3-nm and below, seamlessly interoperates with Synopsys Controller IP for PCIe 7.0 to provide a low-risk solution that designers can use to accelerate time-to-market and efficiently deliver differentiated products that require the 128 GT/s PCIe 7.0 technology.

Key Features

  • Physical Coding Sublayer (PCS) block with PIPE interface
  • Supports PCIe 7.0, encoding, backchannel initialization
  • Lane margining at the receiver
  • Spread-spectrum clocking (SSC)
  • PCIe power management features, including L0P, L1 substate; power gating and power island; DFE bypass option and voltage mode TX
  • The multi-channel PHY macro with single clock and control core for higher density with support for both internal and external reference clock inputs
