9DMU0441 2:4 1.5V PCIe Gen1-2-3 Clock Mux w/Zo=100ohms DATASHEET General Description Features/Benefits The 9DMU0441 is a member of IDT's SOC-Friendly 1.5V Ultra-Low-Power (ULP) PCIe Gen1-2-3 family. It has integrated output terminations providing Zo=100ohms for direct connection to 100ohm transmission lines. 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. • LP-HCSL outputs w/integrated terminations; saves 16 resistors compared to standard HCSL outputs 1.5V operation; 26mW 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 • • • • • Recommended Application 2:4 PCIe Gen1-2-3 clock multiplexer • • Output Features • 4 – Low-Power (LP) HCSL DIF pairs w/Zo=100 Key Specifications • DIF additive cycle-to-cycle jitter
