125 MHz fixed-frequency clock for digital and PHY reference
The DSC1101BI1-125.0000T is a 125 MHz XO (Standard) with CMOS output from Microchip's DSC1101 series. The MEMS resonator base gives it better shock and vibration tolerance than a quartz crystal oscillator — relevant for equipment that ships or operates in high-vibration environments.

Standby function and disable current for power-sensitive designs
The standby (power-down) function pulls the output to high-impedance and drops supply current to 95 µA max. That is low enough to leave the oscillator powered from a battery-backed rail without draining the cell during sleep — useful in remote sensors or battery-operated equipment where the clock domain is gated off between active bursts.
