WebThis technique is known as Spread Spectrum Clocking, or SSC. SSC clocking reduces the EMI level by spreading the radiated energy over a range of frequencies thereby reducing the peak emissions at the PCIe clock center frequency. While SSC clocking reduces EMI interference, it does so at the cost of introducing clock jitter into the PCIe subsystem.
