PCI Express™ Jitter Attenuator  
ICS874001I-02  
DATA SHEET  
General Description  
Features  
The ICS874001I-02 is a high performance 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 jitter attenuator may be required to  
attenuate high frequency random and deterministic jitter  
components from the PLL synthesizer and from the system board.  
The ICS874001I-02 has two different PLL bandwidth modes: 2MHz  
and 3MHz. The 2MHz mode will provide maximum jitter attenuation,  
but with higher PLL tracking skew and spread spectrum modulation  
from the motherboard synthesizer may be attenuated. The 3MHz  
bandwidth provides the best tracking skew and will pass most  
spread profiles, but the jitter attenuation will not be as good as the  
lower bandwidth mode. The 874001I-02 can be set for different  
modes using the F_SELx pins, as shown in Table 3C.  
One differential LVDS output pair  
One differential clock input  
CLK, nCLK can accept the following differential input levels:  
LVPECL, LVDS, LVHSTL, HCSL, SSTL  
Input frequency range: 98MHz to 128MHz  
Output frequency range: 98MHz to 640MHz  
VCO range: 490MHz - 640MHz  
Cycle-to-cycle jitter: 15ps (maximum), 3.3V  
RMS period jitter: 3ps (maximum), 3.3V  
Two bandwidth modes allow the system designer to make jitter  
attenuation/tracking skew design trade-offs  
Full 3.3V or 2.5V operating supply  
-40°C to 85°C ambient operating temperature  
Available in lead-free (RoHS 6) package  
The ICS874001I-02 uses IDT’s 3RD Generation FemtoClock®  
PLL technology to achieve the lowest possible phase noise. The  
device is packaged in a small 20-pin TSSOP package, making it  
ideal for use in space constrained applications such as PCI Express  
add-in cards.
