PCI EXPRESS JITTER ATTENUATOR
ICS874003D-02
IDT / ICS PCI EXPRESS JITTER ATTENUATOR

ICS874003DG-02 REV. A AUGUST 30, 2007
PRELIMINARY
GENERAL DESCRIPTION
The ICS874003D-02 is a high performance Dif-
ferential-to-LVDS 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 ICS874003D-02 has a bandwidth of 2.1MHz. The
2.1MHz provides an intermediate bandwidth that can easily
track triangular spread profiles, while providing good jitter
attenuation.
The ICS874003D-02 uses IDT’s 3rd Generation FemtoClockTM
PLL technology to achive the lowest possible phase noise.
The device is packaged in a 20 Lead TSSOP package, making
it ideal for use in space constrained applications such as PCI
Express add-in cards.
FEATURES
Three Differential LVDS output pairs
One Differential clock input
CLK and nCLK supports the following input types:
LVPECL, LVDS, LVHSTL, SSTL, HCSL
Output frequency range: 98MHz - 320MHz
Input frequency range: 98MHz - 128MHz
VCO range: 490MHz - 640MHz
Cycle-to-cycle jitter: 35ps (maximum)
Supports PCI-Express Spread-Spectrum Clocking
The 2.1MHz bandwidth mode allows the system designer to
make jitter attenuation/tracking skew design trade-offs
3.3V operating supply
0°C to 70°C ambient operating temperature
Available in both standard (RoHS 5) and lead-free (RoHS 6)
packages
