Features
- LP-HCSL output w/integrated terminations; saves 4 resistors compared to standard HCSL output
- 1.5 V operation; 11 mW 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# pin; supports DIF power management
- HCSL differential inputs; can be driven by common clock sources
- 1 MHz to 167 MHz operating frequency
- Space-saving 3x3 mm 16-pin VFQFPN; minimal board space
Description
The 9DMU0141 is a member of IDT's SOC-Friendly 1.5 V Ultra-Low-Power (ULP) PCIe Gen1-2-3 family. It has integrated output terminations providing Zo=100 ohms for direct connection to 100 ohm transmission lines. The output has an OE# pin for optimal system control and power management. The part provides asynchronous or glitch-free switching modes.
