Description
The 9DBU0431 is a member of IDT's 1.5V Ultra-Low-Power
(ULP) PCIe family. The device has 4 output enables for clock
management, and 3 selectable SMBus addresses.

Features/Benefits
• LP-HCSL outputs; save 8 resistors compared to standard
HCSL outputs
• 45mW 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/software 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
• Three selectable SMBus addresses; multiple devices can
easily share an SMBus segment
• Space saving 32-pin 5x5mm VFQFPN; minimal board
space
