Product details

The DSC1001CL1-012.5000 is a MEMS-based XO (Standard) delivering a 12.5 MHz CMOS output from a 4-SMD no-lead package measuring 3.20 mm x 2.50 mm — a drop-in replacement for quartz oscillators where vibration resistance and temperature stability matter more than raw aging specs. It fits under-hood or cabin modules where a quartz can fails from mechanical shock or thermal cycling.

Supply voltage spans 1.8V to 3.3V, so the same BOM line works across a 1.8V MCU rail or a 3.3V peripheral bus without a level translator on the oscillator supply.

Frequently asked questions

Is the DSC1001CL1-012.5000 AEC-Q100 certified?

Yes, it carries AEC-Q100 ratings, which qualifies it for automotive applications.

How does the DSC1001CL1-012.5000 compare to a quartz oscillator at the same frequency?

The MEMS resonator gives it better shock and vibration tolerance than quartz, and the AEC-Q100 qualification means it has passed automotive reliability tests that most quartz oscillators do not carry. The frequency stability is ±50 ppm, which is typical for a standard XO — not as tight as a TCXO, but sufficient for general-purpose clocking in MCU and CAN/FlexRay buses.
