GENERAL DESCRIPTION
The ICS874002-02 is a high performance
Differential-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 ICS874002-02 has 2 PLL bandwidth modes: 2.2MHz
and 3MHz. The 2.2MHz 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 modes.
The 874002-02 can be set for differential modes using the
F_SELx pins as shown in Table 3C.
The ICS874002-02 uses IDT’s 3rd Generation FemtoClockTM
PLL technology to achieve 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.
