DIFFERENTIAL-TO-0.7V DIFFERENTIAL
PCI EXPRESS JITTER ATTENUATOR
ICS871002I-02
IDT / ICS 0.7V DIFFERENTIAL JITTER ATTUNUATOR

ICS871002AGI-02 REV. A SEPTEMBER 14, 2007
PRELIMINARY
GENERAL DESCRIPTION
The ICS871002I-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
ICS871002I-02 has two PLL bandwidth modes: 350kHz and
2000kHz. The 350kHz mode will provide maximum jitter
attenuation, but with higher PLL tracking skew and spread
spectrum modulation from the motherboard synthesizer may
be attenuated. The 2000kHz 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 modes.
The ICS871002I-02 can be set for different modes using the
F_SELx pins as shown in Table 3C.
The ICS871002I-02 uses IDT 3rd Generation FemtoClockTM PLL
technology to achieve the lowest possible phase noise. The
device is packaged in a small 20 Lead TSSOP package, making
it ideal for use in space constrained applications such as PCI
Express add-in cards.
Features
Two 0.7V differential output pairs
One differential clock input
CLK and nCLK supports the following input types: LVPECL,
LVDS, LVHSTL, SSTL, HCSL
