Product details

MEMS oscillator that replaces quartz without a board spin

The DSC1001CI1-012.5000 is a MEMS-based XO (Standard) oscillator that outputs a clean 12.5 MHz CMOS clock from a 1.8V to 3.3V supply rail — no external load capacitors or feedback resistor needed, unlike a quartz crystal. It fits the standard 4-SMD, no-lead footprint (3.20mm x 2.50mm) that quartz oscillators use, so it drops onto the same PCB pads without a layout change.

AEC-Q100 qualification and low-power standby

Power budget and output drive

Maximum active supply current is 6.3 mA at 12.5 MHz — the CMOS output swings rail-to-rail into a standard 15 pF load, so it directly drives the clock input of an MCU or FPGA without a buffer. The 1.8V–3.3V supply range lets it run from the same rail as a 1.8V core or a 3.3V I/O bank without an extra regulator.

Frequently asked questions

Is the DSC1001CI1-012.5000 a drop-in replacement for a quartz oscillator?

Yes — it uses the same 4-SMD, no-lead footprint (3.20mm x 2.50mm) and same pinout as standard quartz oscillators, so it replaces them without a PCB layout change. The MEMS resonator is more shock- and vibration-tolerant than quartz, which matters in automotive and industrial environments.

What is the output frequency and supply voltage of the DSC1001CI1-012.5000?

It outputs a 12.5 MHz CMOS clock and operates from a 1.8V to 3.3V supply. The CMOS output is rail-to-rail, so it drives standard digital logic inputs directly.

Is the DSC1001CI1-012.5000 AEC-Q100 qualified for automotive use?

Yes — it carries an AEC-Q100 rating, which means it has passed the automotive-grade reliability stress tests (temperature cycling, ESD, latch-up) and is suitable for under-hood and cabin applications.
