Product details

125 MHz MEMS oscillator with wide supply range

The DSC1101AI3-125.0000T is a 125 MHz XO (Standard) MEMS oscillator from Microchip's DSC1101 series, delivering a CMOS output over a 2.25V to 3.6V supply range. The MEMS resonator base provides better shock and vibration tolerance than quartz, and faster startup — relevant for portable or industrial equipment subject to mechanical stress.

Standby power-down for duty-cycled designs

A standby (power-down) function drops the supply current to 95 µA max when the clock is not needed, making this oscillator suitable for battery-powered or intermittently operating systems. Active current is 35 mA max at 125 MHz — the disable current is over 350× lower, so a microcontroller that sleeps most of the time can leave the oscillator powered off between wake cycles.

Microchip lists the DSC1101AI3-125.0000T as Active — it is in production and available for new designs, with no announced end-of-life or last-time-buy window.

Frequently asked questions

Does DSC1101AI3-125.0000T support a power-down mode?

Yes, it has a standby (power-down) function that reduces supply current to 95 µA max when the output is disabled.

What is the closest pin-compatible alternative to DSC1101AI3-125.0000T in the DSC1101 family?

The DSC1101 series includes multiple frequency and stability variants in the same 6-VDFN package and pinout — the base product number DSC1101 covers the family. For a different frequency, select the appropriate ordering code from the DSC1101 series.
