5.4.2 IDT ICS9DB102 1-to-2 Differential Clock Driver
IDT ICS9DB102 is two output clock buffer for PCIe Gen1 & Gen2 with HCSL current mode differential
outputs.
Device zero-delay buffer supports PCI Express clocking requirements. The ICS9DB102 is driven by a
differential compliant input 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.
