Product details

The DSC1121DM2-019.2000: The MEMS resonator gives it better shock and vibration immunity than a quartz crystal, and the 2.25V to 3.6V supply range means it runs from a 3.3V or 2.5V rail without an extra regulator — the Enable/Disable function lets the system gate the clock for power savings, drawing 22 mA max when disabled.

6-SMD no-lead package and board-fit note

Housed in a 6-SMD no-lead package measuring 2.50 mm x 2.00 mm with a seated height of 0.90 mm — the 0.098" x 0.079" footprint matches the standard 2.5 x 2.0 mm oscillator land pattern, so the board layout is the same as a quartz XO of the same size.

Frequently asked questions

What is the datasheet for DSC1121DM2-019.2000?

Engineers need the datasheet to verify pinout, timing, and electrical characteristics for design-in.

How much does DSC1121DM2-019.2000 cost?

Buyers compare pricing across distributors to get the best unit cost for BOM planning.

Is DSC1121DM2-019.2000 in stock at DigiKey?

Immediate availability determines if the part can be sourced without risking production delays.

What is the replacement for DSC1121DM2-019.2000?

If the part becomes scarce, engineers need a compatible drop-in replacement to avoid redesign.

What is the output type of DSC1121DM2-019.2000?

Designers must ensure the output (CMOS) matches the load capacitance and termination of the receiving IC.

What is the lead time for DSC1121DM2-019.2000?

Long lead times can impact project schedules, so sourcing buyers need accurate lead time estimates.
