Description
The 9DBU0231 is a member of IDT's 1.5V Ultra-Low-Power
(ULP) PCIe family. The device has 2 output enables for clock
management.

Features/Benefits
• LP-HCSL outputs; save 4 resistors compared to standard
HCSL outputs
• 35mW typical power consumption in PLL mode; eliminates
thermal concerns
• Spread Spectrum (SS) compatible; allows SS for EMI
reduction
• OE# pins; support DIF power management
• HCSL compatible differential input; can be driven by
common clock sources
• SMBus-selectable features; optimize signal integrity to
application
• slew rate for each output
• differential output amplitude
• Pin/SMBus selectable PLL bandwidth and PLL Bypass;
optimize PLL to application
• Outputs blocked until PLL is locked; clean system start-up
• Device contains default configuration; SMBus interface not
required for device control
• 3.3V tolerant SMBus interface works with legacy controllers
• Space saving 24-pin 4x4mm VFQFPN; minimal board
space
