Description

The 874001I-05 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 874001I-05 has a bandwidth of 6MHz with <1dB peaking, easily meeting PCI Express® Gen2 PLL requirements. The 874001I-05 uses IDT's 3RD Generation FemtoClock® PLL technology to achieve the lowest possible phase noise. The device is packaged in a small 20-pin TSSOP package, making it ideal for use in space constrained applications such as PCI Express® add-in cards.
