9FGV0441AKLF

The 9FGV0441 is an 4-output very low power clock generator for PCIe Gen1–4 applications with integrated output terminations providing Zo = 100Ω. The device has 4 output enables for clock management and supports 2 different spread spectrum levels in addition to spread off.

Key Features

• Integrated terminations provide 100Ω differential Zo; reduced component count and board space
• 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 5 x 5 mm 32-VFQFPN; minimal board space
• Selectable SMBus addresses; multiple devices can easily share an SMBus segment
