2:1 1.5V PCIe Gen1-2-3 Clock Mux

9DMU0131

General Description

The 9DMU0131 is a member of IDT's SOC-Friendly 1.5V

Ultra-Low-Power (ULP) PCIe Gen1-2-3 family. The output

has an OE# pin for optimal system control and power

management. The part provides asynchronous or glitch-free

switching modes.

Recommended Application

2:1 1.5V PCIe Gen1-2-3 Clock Mux

Output Features

• 1 – Low-Power (LP) HCSL DIF pair

Key Specifications

• DIF additive cycle-to-cycle jitter <5ps

• DIF phase jitter is PCIe Gen1-2-3 compliant

• 125MHz additive phase jitter 535fs rms typical (12kHz to

20MHz)

Features/Benefits

• LP-HCSL output; saves 2 resistors compared to standard

HCSL output

• 1.5V operation; 11mW 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 167MHz operating frequency

• Space saving 16-pin 3x3mm VFQFPN; minimal board

space
