9FG830
IDT Eight Output Differential Frequency Generator for PCIe Gen3 and QPI
1680C—08/26/10
Eight Output Differential Frequency Generator
for PCIe Gen3 and QPI
1
DATASHEET
General Description:
The 9FG830 is a Frequency Timing Generator that provides 8
HSCL 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.
Recommended Application:
8 Output Differential Output Frequency Generator for PCIe Gen3
and QPI
Output Features:
8 - 0.7V current mode differential HSCL output pairs
1 - 3.3V LVTTL REF output
Features/Benefits:
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
Key Specifications:
Cycle-to-cycle jitter: < 50ps with 25MHz input
Output-to-output skew: <50ps
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
