The 874001I-02 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-02 has two different PLL bandwidth modes: 2MHz and 3MHz. The 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 mode. The 874001I-02 can be set for different modes using the F_SELx pins, as shown in Table 3C. The 874001I-02 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.
