PCI Express® Jitter Attenuator

The 874003DI-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 874003DI-02 has a bandwidth of 3MHz. The 3MHz provides an intermediate bandwidth that can easily track triangular spread profiles, while providing good jitter attenuation. The 874003DI-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.
