Product details

MEMS oscillator for harsh-environment clocking

AEC-Q100 qualified — the DSC1001CL1-001.8432T meets automotive IC stress and reliability standards, so it fits engine bay, transmission, and chassis-domain ECUs without a separate screening step. Supply voltage spans 1.8V to 3.3V — a single BOM line covers 1.8V, 2.5V, and 3.3V logic rails; no voltage variant needed when the same board ships with different core supplies.

Standby power-down and package footprint

The Standby (Power Down) function drops supply current to 15 µA max — useful for battery-backed modules that need to stop the clock without removing power. 4-SMD, No Lead package, 3.20 mm x 2.50 mm, 0.90 mm seated height — standard 4-pin footprint that matches many quartz XO land patterns, so a board designed for a 3.2 x 2.5 mm crystal oscillator can take this MEMS part without a layout change.

Frequently asked questions

Can DSC1001CL1-001.8432T replace a standard quartz crystal oscillator on my board?

Yes, if the board uses a 3.2 mm x 2.50 mm 4-pin CMOS oscillator footprint. The DSC1001CL1-001.8432T is a MEMS-based XO (Standard) with CMOS output, so it drops into the same land pattern as a quartz XO of the same size. No external load capacitors or feedback resistor needed — the MEMS resonator is self-contained. Confirm the supply voltage (1.8V–3.3V) and frequency (1.8432 MHz) match your BOM.
