The 9FGV0241AKILFT is a 2-output very low power frequency generator for PCIe Gen1–4applications with integrated output terminations providing Zo=100 Ω. The device has 2 output enables for clock management and supports 2 different spread spectrum levels in addtion to spread off.
Feature
PCIe Gen1–4 compliant
Integrated terminations provide 100 Ω differential Zo: reduced component count and board space
1.8 V 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 25 MHz crystal; supports tight ppm with 0 ppm synthesis error
Configuration can be accomplished with strapping pins: SMBus interface not required for device control
3.3 V tolerant SMBus interface works with legacy controllers
