7-output PCIe Gen1 Clock Synthesizer with 3 PCI Outputs

The 9FG107 is a Synthesizer 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 device 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. 9FG107 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.

Features

  • Generates common CPU/PCI Express frequencies from 14.318 MHz or 25 MHz
  • Crystal or reference input
  • 7 - 0.7 V HCSL differential output pairs
  • 3 - 33 MHz 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
