Through the years, PCI Express® (PCIe®) protocol has evolved to accommodate the needs of higher speeds, imposing stringent requirements for a reliable clock source. We offer a comprehensive line of PCIe Gen 5 compliant oscillators, clock generators and buffers to address this need. Our timing parts not only meet the PCIe jitter requirements, but also allow allocation of up to 70% of total jitter margin to the rest of the system. With our highly integrated single-chip solutions, you can reduce component count and board area without sacrificing performance.

Key Features

  • PCIe Gen 1/2/3/4/5 compliant
