General Description
The ICS874003-04 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
ExpressTM 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 ICS874003-04 has a bandwidth of 6.8MHz.
The 6.8MHz provides a high bandwidth that can easily track
triangular spread profiles, while providing jitter attenuation.
The ICS874003-04 uses IDT’s 3rd Generation FemtoClock™ 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.
