RENESAS 9FG830AGILFT

The 9FG830 is a Frequency Timing Generator that provides 8 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 9FG830 also outputs a copy of the reference clock. Complete control of the device is available via strapping pins or via the SMBus interface.

• Pin-to-Pin with 9FG108D; 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
• Three spread spectrum modes: - 0.5%, +/ - 0.25%, and off; EMI reduction
• 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
• 8 * 0.7V current mode differential HCSL output pairs
• 1 - 3.3V LVTTL REF output
• Cycle-to-cycle jitter: <50 ps with 25MHz input
• Output-to-output skew: <50 ps
• Phase jitter: PCIe Gen3 < 1ps rms
• Phase jitter: QPI 9.6GB/s < 0.2ps rms
• 10 ppm synthesis error with 25MHz input and Spread Off

• 8 Output Differential Output Frequency Generator for PCIe Gen3 and QPI
