Product details

The supply voltage spans 2.25V to 3.6V, so a single oscillator works on a 2.5V or 3.3V rail without an intermediate regulator; the Enable/Disable function pulls the output to high-Z, cutting supply current to 22 mA max when the clock is gated.

Housed in a 6-SMD, No Lead Exposed Pad package measuring 7.00mm x 5.00mm with a seated height of 0.90mm, this oscillator is a drop-in replacement for standard 7x5 mm crystal oscillators — the same footprint, no board spin.

Frequently asked questions

Is the DSC1121AM2-040.0000T a drop-in replacement for a standard 40 MHz crystal oscillator?

Yes — the 7.00mm x 5.00mm 6-SMD package and CMOS output make it footprint- and function-compatible with standard 7x5 mm crystal oscillators. The MEMS resonator inside is more shock-resistant than quartz, so it handles vibration environments better, but the electrical interface is identical.

Does the DSC1121AM2-040.0000T work on a 3.3V supply?

Yes — the supply voltage range of 2.25V to 3.6V covers both 2.5V and 3.3V rails directly. No external LDO or level shifter is needed.
