General Description
The 9DMU0431 is a member of IDT's SOC-Friendly 1.5V
Ultra-Low-Power (ULP) PCIe Gen1-2-3 family. Each of the 4
outputs has its own dedicated OE# pin for optimal system
control and power management. The part provides
asynchronous and glitch-free switching modes.

Features/Benefits
• LP-HCSL outputs; save 8 resistors compared to standard
HCSL outputs
• 1.5V operation; 31mW typical power consumption
• Selectable asynchronous or glitch-free switching; allows
the mux to be selected at power up even if both inputs are
not running, then transition to glitch-free switching mode
• Spread Spectrum Compatible; supports EMI reduction
• OE# pins; support DIF power management
• HCSL differential inputs; can be driven by common clock
sources
• 1MHz to 167MHz operating frequency
• Space saving 24-pin 4x4mm VFQFPN; minimal board
space
