Clock Generator for Intel PCIe
Description
PI6C410B is a high-speed, low-noise clock generator designed to
work with Intel Server PCIe Chipset. The Spread Spectrum PLL
based clock generator reduces EMI emission and supports a wide
range of frequencies.
Jitter Performance
• < 85ps Cycle-to-Cycle CPU clock jitter
• < 350ps Cycle-to-Cycle 48MHz clock jitter
• < 500ps Cycle-to-Cycle PCI clock jitter
• < 125ps Cycle-to-Cycle SRC clock jitter
• < 1000ps Cycle-to-Cycle REF clock jitter
Skew Performance
• < 100ps Output to output CPU clock skew
• < 500ps Output to output PCI clock skew
• < 250ps Output to output SRC clock skew
