Product details

Active MEMS oscillator for 72 MHz clock trees

The DSC1121DL2-072.0000 is an active-production MEMS-based XO (Standard) from Microchip Technology, delivering a 72 MHz CMOS output with ±25 ppm frequency stability across -40 to +105°C.

Supply, current, and package constraints

Operates from a single 2.25V to 3.6V rail with a maximum supply current of 35 mA, fitting common 2.5V, 3.0V, or 3.3V system rails without a dedicated regulator. Packaged in a 6-VDFN measuring 2.50mm x 2.00mm with a seated height of 0.90mm — the 0.50 mm pitch land pattern demands careful solder-paste stencil design to avoid bridging.

Sourcing and lifecycle — active production

Product status is Active — the DSC1121 series remains in volume production with no announced last-time-buy or obsolescence notice.

Frequently asked questions

Is DSC1121DL2-072.0000 a direct replacement for a 72 MHz crystal oscillator?

No — this is a MEMS-based XO (complete oscillator with integrated resonator), not a bare quartz crystal. A crystal requires an external oscillator circuit; the DSC1121DL2-072.0000 outputs a rail-to-rail CMOS clock and includes an Enable/Disable pin, so it replaces a crystal-plus-oscillator stage, not the crystal alone.

What is the closest pin-compatible alternative to the DSC1121DL2-072.0000?

Within the DSC1121 series, the same 6-VDFN package and pinout is shared across all frequencies. The closest functional sibling is any other DSC1121DL2 variant with the same output format and supply range — the order code suffix encodes frequency, stability, and temperature grade, so a direct drop-in requires matching those three parameters.
