Features
- LP-HCSL output with integrated terminations; saves four resistors compared to standard HCSL output
- 1.8V operation; 12mW 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
- 1MHz to 200MHz operating frequency
- Configuration can be accomplished with strapping pins; SMBus interface is not required for device control
- Space-saving 3mm x 3mm 16-VFQFPN; minimal board space
Description
The 9DMV0141 is a 1.8V very-low power PCIe Gen 1–5 clock mux. The device has integrated output terminations for direct connection to 100Ω transmission lines. The output has an OE# pin for optimal system control and power management. The parts provide asynchronous or glitch-free switching modes.
