PCI Express® Jitter Attenuator

The 874003-05 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 874003-05 has a bandwidth of 6.2MHz with <1dB peaking, easily meeting PCI Express® Gen2 PLL requirements. The 874003-05 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.
