The 9FG430 is a Frequency Timing Generator that provides 4 HCSL differential output pairs. These outputs support PCI-Express Gen3, and QPI applications. The part supports Spread Spectrum and synthesizes several additional output frequencies from either a 14.31818 MHz crystal, a 25 MHz crystal or reference input clock. The 9FG430 also outputs a copy of the reference clock. Complete control of the device is available via strapping pins or via the SMBus inteface.

特性

  • 4 - 0.7 V current mode differential HCSL output pairs
  • 1 - 3.3 V LVTTL REF output
  • Pin-to-Pin with 9FG104D/Easy upgrade to PCIe Gen3
  • Generates common frequencies from 14.318 MHz or 25 MHz; single part supports mulitple applications
  • Provides copy of reference output; eleminates need for additional crystal or oscillator
  • Unused outputs may be disabled in Hi-Z save system power
  • Device may be configured by SMBus and/or strap pins; can be used in systems without SMBus
  • Cycle-to-cycle jitter: < 50 ps with 25 MHz input
  • Output-to-output skew: <50 ps
  • Phase jitter: PCIe Gen3 < 1 ps RMS
  • Phase jitter: QPI 9.6 GB/s < 0.2 ps RMS
  • 10 ppm synthesis error with 25 MHz input and Spread Off
