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 interface.
