9FGU0231AKILF

The 9FGU0231 is a member of IDT’s 1.5 V Ultra-Low-Power PCIe clock family. The device has 2 output enables for clock management, 2 different spread spectrum levels in addition to spread off, and 2 selectable SMBus addresses.

• LP-HCSL outputs; save 4 resistors compared to standard PCIe devices
• 23 mW typical power consumption; reduced thermal concerns
• Outputs can optionally be supplied from any voltage between 1.05 and 1.5 V; maximum power savings
• OE# pins; support DIF power management
• 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 such as the IDT 603-25-150 (25 MHz); 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
• Space saving 4x4 mm 24-pin VFQFPN; minimal board space
• Selectable SMBus
