Product details

The DSC1121AM1-041.5000: This oscillator can be deployed in avionics, satellite, downhole drilling, or missile guidance systems where the ambient temperature swings well beyond industrial limits.

Supply voltage flexibility and enable/disable

The supply voltage range is 2.25 V to 3.6 V, covering 2.5 V and 3.3 V logic rails without a separate regulator — one BOM line serves multiple voltage domains. This matters for battery-powered or thermal-constrained designs where every milliampere counts.

The 6-VDFN exposed pad package measures 7.00 mm x 5.00 mm with a seated height of 0.90 mm.

Frequently asked questions

Does the DSC1121AM1-041.5000 have an enable/disable function?

Yes, the function is Enable/Disable. When disabled, the maximum supply current drops from 35 mA to 22 mA.

What is the output type of the DSC1121AM1-041.5000?

The output is CMOS, compatible with standard digital logic inputs.
