General Description:

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.

Features/Benefits:

• 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
