8-output PCIe Gen1-2 Synthesizer

9FG108 is a Synthesizer that provides 8 differential output pairs that are compliant to the Intel CK410 specification. It also 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 50 ps and output-to-output skew of less than 65 ps.

Features

  • Generates common frequencies from 14.318 MHz or 25 MHz
  • Crystal or reference input
  • 8 - 0.7 V HCSL differential output pairs
  • 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
  • Programmable OE Polarity
  • M/N Programming
