PCI Express Solutions
Field-Proven, Interoperable, and Standards-Compliant Portfolio
PCI Express Solutions
PCI Express (PCIe) is a widely deployed bus interconnect
interface that is commonly used in server platforms.
Increasingly, it is also used as a storage and GPU interconnect
solution. PCIe Gen3 supports 8 GT/s of throughput per PCIe
lane, and Gen4 supports 16 GT/s. Typical implementations
utilize ×2, ×4, ×8, and ×16 lane width interconnect
configurations—directly from the host root complex or through
PCIe switches to endpoint PCIe devices.
Microsemi is a leader in PCIe, having introduced multiple
industry firsts. Highlights include:
• PCIe Gen3 SAS/SATA RAID controller
• The industry’s highest density and lowest power Gen3
PCIe Switches, Switchtec PSX and PFX
• PCIe Gen3 NVMe Flash controller (Flashtec
™
), followed by
a second-generation introduction of the industry’s fastest
PCIe Gen3 NVMe SSD controllers
• PCIe Gen3 redriver with EQNOX
™
adaptive equalization
• Flash-based FPGAs and SoCs used in CPLD functions
with integrated PCIe endpoint implementations
Microsemi offers a flexible product portfolio to intelligently
design your PCIe system for data center, communications,
defense, and industrial applications. Our industry-leading
PCIe solutions include storage and fanout switches, NVMe
controllers, NVRAM drives, redrivers, and timing solutions,
