ICS9DB306
PCI EXPRESS,
JITTER ATTENUATOR
GENERAL DESCRIPTION
The ICS9DB306 is a high performance 1-to-6
Differential-to LVPECL 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
synthesizer. In these systems, a zero delay buffer may be
required to attenuate high frequency random and deterministic
jitter components from the PLL synthesizer and from the system
board. The ICS9DB306 has 2 PLL bandwidth modes. In low
bandwidth mode, the PLL loop BW is about 500kHz and this
setting will attenuate much of the jitter from the reference clock
input while being high enough to pass a triangular input spread
spectrum profile. There is also a high bandwidth mode which
sets the PLL bandwidth at 1MHz which will pass more spread
spectrum modulation.
For serdes which have x30 reference multipliers instead of x25
multipliers, 5 of the 6 PCI Express outputs (PCIEX1:5) can be
set for 125MHz instead of 100MHz by configuring the appropri-
ate frequency select pins (FS0:1). Output PCIEX0 will always
run at the reference clock frequency (usually 100MHz) in desk-
top PC PCI Express Applications.
