Product details

This operating range covers avionics, downhole instrumentation, satellite subsystems, and missile guidance — environments where a quartz oscillator's aging or vibration sensitivity would drift the clock edge.

Supply voltage range is 2.25V to 3.6V, covering 2.5V and 3.3V rails without an external regulator — the wide tolerance simplifies BOM consolidation across mixed-voltage designs.

6-SMD package and board integration

Housed in a 6-SMD, No Lead Exposed Pad package measuring 7.00mm x 5.00mm with a seated height of 0.90mm — this is a standard footprint that matches many quartz oscillator pads, easing drop-in replacement.

Frequently asked questions

Does DSC1121AM1-100.0000 have a disable function and what is its logic?

Yes, it has an Enable/Disable function. When disabled, the output is tri-stated, which allows the oscillator to be used in shared-clock or power-saving applications.

Can DSC1121AM1-100.0000 replace a standard quartz oscillator of the same frequency?

Yes, the 100 MHz CMOS output and standard 7.00mm x 5.00mm 6-SMD footprint are pin-compatible with many quartz oscillators. The MEMS resonator offers better shock and vibration tolerance than quartz, which can be an advantage in harsh environments.
