Description

The 9FGV0441 is an 4-output very low power clock generator for PCIe Gen 1, 2, 3 and 4 applications with integrated output terminations providing Zo = 100. The device has 4 output enables for clock management and supports 2 different spread spectrum levels in addition to spread off.

Features/Benefits

• Integrated terminations provide 100 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 32-pin 5x5 mm VFQFPN; 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 w/Zo=100

• 1 – 1.8V LVCMOS REF output w/ Wake-On-Lan (WOL) support
