Microchip Technology has unveiled the world’s first PCIe 5.0 switch ICs. The Switchtec PFX PCIe 5.0 family of switches are designed for internal connections in high-performance computers, NVMe storage and networking equipment. They can be used in conjunction with PCIe Gen 5 compliant XpressConnect sync restorers.
The Switchtec PFX PCIe 5.0 family includes high density, high reliability switches with 28 to 100 lanes and up to 48 nontransparent bridges (NTBs). The manufacturer notes support for hot plugging and secure boot authentication.
Complex topologies and the challenge of maintaining signal integrity at 32 GT / s data rates pose significant challenges when designing and debugging PCIe 5.0 systems. To simplify their solution, the Switchtec PFX PCIe 5.0 switches are equipped with a full suite of debugging and diagnostic features, including embedded PCIe analyzers that support transaction-level packet generation and analysis (TLP), and serial-to-parallel and parallel-to-serial converter monitoring tools that do not affect their work. In addition, the manufacturer offers design documentation, sample projects, evaluation boards, and other developer support tools. Evaluation samples of Switchtec PFX PCIe 5.0 switches are now available.
