Description

PCIE BUFFER
ICS9FG107 is a Frequency Timing Generator that provides 7 differential output pairs that are compliant to the Intel CK409/ CK410 specification. It provides support for PCI-Express, next generation I/O, and SATA. The part synthesizes several output frequencies from either a 14.31818 Mhz crystal or a 25 MHz crystal. The ICS9FG107 can also be driven by a reference input clock instead of a crystal. It provides outputs with cycle-to-cycle jitter of less than 85 ps and output-to-output skew of less than 85 ps. ICS9FG107 also provides a copy of the reference clock and 3 33 MHz PCI output clocks. Frequency selection can be accomplished via strap pins or SMBus control.? Generates common CPU/PCI Express frequencies from 14.318 MHz or 25 MHz ? Crystal or reference input ? 7 - 0.7V current-mode differential output pairs ? 3 - 33MHz PCI outputs ? 1 - REFOUT ? Supports Serial-ATA at 100 MHz ? Two spread spectrum modes: 0 to -0.5 downspread and +/-0.25% centerspread ? Unused inputs may be disabled in either driven or Hi-Z state for power management.
