Product details

MEMS oscillator for extreme-temperature clocking

The DSC1121DM2-014.7456 is a MEMS-based XO (Standard) from Microchip's DSC1121 series, delivering a 14.7456 MHz CMOS output with ±25ppm frequency stability across the full -55°C to 125°C military temperature range. The MEMS resonator gives this oscillator a significant reliability edge over quartz in high-shock and high-vibration environments — no crystal to crack or age-shift under thermal cycling. With a 2.25V to 3.6V supply range, it can be powered directly from a 3.3V or 2.5V rail without an intermediate regulator, saving a component and a PCB via.

Enable/disable function and output drive

CMOS output drives standard logic families directly; the 35mA max supply current is the total device draw at full output load, so budget this into the rail's current capacity.

Housed in a 6-VDFN package measuring 2.50mm x 2.00mm with a 0.90mm seated height, this oscillator fits tight PCB layouts — the 0.098" x 0.079" footprint is roughly the size of a 0805 capacitor.

Frequently asked questions

Where can I buy DSC1121DM2-014.7456 and how do I get a price?

This part is Active and available to order. Submit an RFQ with your target quantity — we source through independent distribution and confirm availability and pricing per your BOM line. No stock-holding claim; quoted to order.

Is DSC1121DM2-014.7456 a direct replacement for a quartz crystal oscillator?

No — this is a MEMS-based XO (Standard) with an integrated resonator and CMOS output. It is a drop-in replacement for a quartz crystal oscillator module (same package and pinout), but not for a bare quartz crystal, which requires an external load-capacitance circuit. The MEMS construction offers better shock and vibration tolerance than quartz.

What is the output type of DSC1121DM2-014.7456?

The output is CMOS, which drives standard logic families directly without external level translation. The enable/disable function allows the output to be tri-stated for power management.
