Datasheet
Two Output Differential Buffer for PCIe Gen1 & Gen2
Description
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.
