Product details

40 MHz MEMS oscillator for wide-temperature designs

Its 2.25V to 3.6V supply range means it can run directly off a 2.5V or 3.3V rail without an extra regulator, and the ±50 ppm frequency stability keeps the clock edge within tight timing budgets across temperature.

Military temperature grade and deployment fit

The 6-SMD package (3.20mm x 2.50mm) with no leads keeps the footprint small and the thermal path short — the solder joints carry the heat into the board plane.

Low power and standby function for battery-operated gear

No last-time-buy window is pending, and no successor has been announced.

Frequently asked questions

What is the frequency of the DSC1101CM1-040.0000T?

40 MHz.

What is the output type of the DSC1101CM1-040.0000T?

CMOS.

What is the closest pin-compatible alternative to the DSC1101CM1-040.0000T in the DSC1101 series?

Any other DSC1101-series oscillator with the same 6-SMD package, same supply range, and the same frequency can be considered pin-compatible, provided the output type and stability grade match the application requirements. The base product number DSC1101 covers the family; the specific suffix determines frequency, stability, and temperature range.
