9DMV0431 fiche technique
2:4 1.8V PCIe Gen1-2-3 Clock Mux
9DMV0431
DATASHEET
General Description
The 9DMV0431 is a member of IDT's SOC-Friendly 1.8V
Very-Low-Power (VLP) 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.
Recommended Application
2:4 PCIe Gen1-2-3 clock multiplexer
Output Features
4 -Low-Power (LP) HCSL DIF pairs
Key Specifications
DIF additive cycle-to-cycle jitter <5ps
DIF phase jitter is PCIe Gen1-2-3 compliant
Additive phase jitter @ 125MHz: 420fs rms typical (12kHz
to 20MHz)
DIF output-to-output skew <50ps
Features/Benefits
LP-HCSL outputs; save 8 resistors compared to standard
HCSL outputs
1.8V operation; 36mW 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 200MHz operating frequency
Space saving 24-pin 4x4mm VFQFPN; minimal board
space
