Product details

10 MHz MEMS oscillator with full automotive temp range

The DSC1121CM1-010.0000 is a 10 MHz MEMS-based XO (Standard) from Microchip's DSC1121 series, delivering a CMOS output with ±50 ppm frequency stability across the full -55°C to 125°C military-automotive temperature band.

The 2.25V to 3.6V supply range means the same part runs on a 2.5V or 3.3V rail without a separate regulator — a single BOM line covers both voltage domains.

Package, footprint, and hand-solderability

Housed in a 6-SMD no-lead package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm — a compact footprint that fits tight PCB layouts. The no-lead package has exposed pads on the bottom; hand-soldering is possible with a hot-air station and a fine-tip iron for the perimeter pads, but a reflow profile is cleaner for production volumes.

Frequently asked questions

Where can I buy DSC1121CM1-010.0000 online and how do I get a price?

This part is active and available through independent distribution. No stock-holding claim — every order is sourced per your BOM.

Is DSC1121CM1-010.0000 a drop-in replacement for a quartz oscillator?

Functionally yes — it outputs a CMOS clock at 10 MHz with ±50 ppm stability, same as a quartz XO. The MEMS resonator is more shock- and vibration-tolerant than quartz, and the -55°C to 125°C range exceeds most quartz parts. Pin-compatible with standard 6-pin SMD oscillators, but confirm the footprint matches your PCB land pattern.

Can DSC1121CM1-010.0000 operate at 2.5V supply?

Yes — the supply range is 2.25V to 3.6V, so a 2.5V rail is within spec. No external regulator needed.

Does DSC1121CM1-010.0000 require external capacitors?

No — as a MEMS oscillator, the timing element is internal. Unlike a quartz crystal, no external load capacitors are needed. The CMOS output drives the load directly.
