Product details

What this MEMS oscillator brings to your board

The DSC1001CI2-025.0000T is a 25 MHz MEMS-based XO (Standard) from Microchip's DSC1001 series, delivering a CMOS output that directly clocks MCUs, FPGAs, or SoCs without external level translation. The supply voltage range of 1.8V to 3.3V lets it run from a single rail common in automotive and portable designs, simplifying the power tree.

Standby power-down and package fit

Housed in a 4-SMD, no-lead package measuring 3.20mm x 2.50mm with a seated height of 0.88mm, it fits tight PCB layouts common in automotive ECUs and portable instrumentation.

Frequently asked questions

Is the DSC1001CI2-025.0000T AEC-Q100 qualified?

Yes — the ratings field explicitly lists AEC-Q100. That means it has passed the automotive-grade reliability stress tests (temperature cycling, ESD, latch-up) and is suitable for under-hood or cabin electronics.

What supply voltage range does the DSC1001CI2-025.0000T accept?

It operates from 1.8V to 3.3V, covering the three most common digital logic rails without needing a separate regulator or level translator.

How does the DSC1001CI2-025.0000T compare to a standard quartz oscillator?

The base resonator is MEMS, not quartz. MEMS oscillators typically offer better shock and vibration tolerance, faster start-up, and smaller footprint for the same frequency stability (±25 ppm,). The trade-off is that quartz may have lower phase noise in some narrow-band applications, but for general-purpose clocking of an MCU or SoC, the MEMS part is a drop-in replacement with improved ruggedness.
