Product details

MEMS oscillator for harsh-environment clocking

The DSC1121DM3-032.0000T is a MEMS-based XO (Standard) from Microchip's DSC1121 series, delivering a 32 MHz CMOS output with ±20 ppm frequency stability across the full -55°C to 125°C military temperature range. Unlike quartz-based oscillators, the MEMS resonator handles shock and vibration better — relevant for avionics, downhole tools, or satellite payloads where a crystal can fracture or drift under G-load.

Housed in a 6-SMD no-lead package measuring 2.50 mm x 2.00 mm with a seated height of 0.90 mm — the compact footprint fits tight PCB layouts, but the no-lead terminations require a solder-paste stencil aperture matched to the pad geometry for reliable reflow.

The DSC1121 series is a current production line from Microchip, so this part can be designed in without worrying about a near-term discontinuation.

Frequently asked questions

What is the difference between the DSC1121 and DSC1122 series?

The DSC1121 is a standard XO with CMOS output; the DSC1122 is a spread-spectrum version intended for EMI reduction. For a 32 MHz clock that needs tight frequency stability without spread-spectrum modulation, the DSC1121 is the correct choice.

Can I replace a quartz oscillator with the DSC1121DM3-032.0000T?

Yes — the DSC1121 is a drop-in MEMS replacement for standard 32 MHz CMOS quartz oscillators in the same 6-SMD footprint. The MEMS resonator offers better shock and vibration tolerance and faster startup, but the output type, supply voltage range, and frequency stability are compatible with most quartz-based designs.

Is the DSC1121DM3-032.0000T RoHS compliant?

The part is listed with a standard RoHS compliance status — no non-RoHS variant is indicated in the product record. Confirm the specific RoHS certificate with the datasheet or your Microchip contact for formal documentation.
