Description
The 9FGV0431 is a 4-output very low-power clock generator for PCIe Gen 1, 2, 3 and 4 applications. The device has 4 output enables for clock management and supports 2 different spread spectrum levels in addition to spread off.

Features/Benefits
• 1.8V operation; reduced power consumption
• OE# pins; support DIF power management
• LP-HCSL differential clock outputs; reduced power and board space
• Programmable Slew rate for each output; allows tuning for various line lengths
• Programmable output amplitude; allows tuning for various application environments
• DIF outputs blocked until PLL is locked; clean system start-up
• Selectable 0%, -0.25% or -0.5% spread on DIF outputs; reduces EMI
• External 25MHz crystal; supports tight ppm with 0 ppm synthesis error
• Configuration can be accomplished with strapping pins; SMBus interface not required for device control
• 3.3V tolerant SMBus interface works with legacy controllers
• Space saving 32-pin 5x5 mm MLF; minimal board space
• Selectable SMBus addresses; multiple devices can easily share an SMBus segment

Output Features
• 4 – 0.7V low-power HCSL-compatible (LP-HCSL) DIF pairs
• 1 – 1.8V LVCMOS REF output w/Wake-On-Lan

Recommended Application
