IDT ICS9DB102
The ICS9DB102 zero-delay buffer supports PCI Express clocking requirements. The ICS9DB102 is driven by a differential SRC output pair from an ICS CK410/CK505-compliant main clock. It attenuates jitter on the input clock and has a selectable PLL Band Width to maximize performance in systems with or without Spread-Spectrum clocking.DESCRIPTION
