ICS874005-04
DESCRIPTION
The ICS874005-04 is a high performance Diff IC S erential-to-LVDS Jitter Attenuator designed for use Hi Per Clock S™ 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 ponents from the PLL synthesizer and from the system board. The ICS874005-04 has 2 PLL bandwidth modes: 300k Hz and 2MHz. The 300k Hz mode will provide maximum jitter attenuation, but higher PLL tracking skew and spread spectrum modulation from the motherboard synthesizer may be attenuated. The 2MHz bandwidth provides the best tracking skew and will pass most spread profiles. The ICS874005-04 supports Serdes reference clock frequencies of 100MHz, 125MHz and 250MHz. The ICS874005-04 uses IDT’s 3 Generation Femto Clock PLL technology to achive the lowest possible...
