synthesizer. In these systems, a jitter-attenuating device may be
necessary in order to reduce high frequency random and
deterministic jitter components from the PLL synthesizer and from
the system board. The ICS9DB206 has two PLL bandwidth modes.
In low bandwidth mode, the PLL loop bandwidth is 500kHz. This
setting offers the best jitter attenuation and is still high enough to
pass a triangular input spread spectrum profile. In high bandwidth
mode, the PLL bandwidth is at 1MHz and allows the PLL to pass
more spread spectrum modulation.
For serdes which have x10 reference multipliers instead of x12.5
multipliers, 5 of the 6 PCI Express outputs (PCIEX1:5) can be
set for 125MHz instead of 100MHz by configuring the appropriate
frequency select pins (FS0:1). Output PCIEX0 will always run at
the reference clock frequency (usually 100MHz) in desktop PC
PCI Express Applications.

The ICS9DB206 is a high perfromance 1-to-6
Differential-to-HCSL Jitter Attenuator designed for
use in PCI Express™ systems. In some PCI Express
systems, such as those found in desktop PCs, the
PCI Express clocks are generated from a low
bandwidth, high phase noise PLL frequency
