Product details

Supply range and standby for battery-backed designs

Runs on 1.7V to 3.6V — one rail covers the full 1.8V and 3.3V logic families without a level translator.

The MEMS die is sourced in volume, so lead times are typically shorter than quartz equivalents.

4-SMD no-lead package, 3.20mm x 2.50mm, 0.90mm seated height — same footprint as a standard 3.2x2.5 mm quartz oscillator. The MEMS die and ASIC are stacked inside a single ceramic cavity, so the pad layout is identical to the quartz part it replaces. No via-in-pad needed; the centre pad is a thermal/mechanical anchor, not an electrical connection.

Frequently asked questions

Is DSC1003CI5-020.0000T a good replacement for a quartz oscillator?

Yes — same 3.2x2.5 mm footprint, same CMOS output, same 20 MHz frequency. The MEMS resonator is inherently more shock- and vibration-tolerant than quartz, and the ±10 ppm stability holds across temperature without the aging drift of a crystal. No external load capacitors needed; the oscillator is self-contained. For a BOM line that currently uses a quartz XO, this is a pin-compatible swap that improves reliability in high-vibration environments like engine ECUs or transmission controllers.
