Product details

100 MHz MEMS oscillator with tight stability

The DSC1121AI5-100.0000T delivers a 100 MHz clock from a MEMS resonator, not a quartz crystal — that means faster startup and better tolerance to shock and vibration compared to a traditional XO.

Supply voltage and output compatibility

Runs on a 2.25V to 3.6V supply rail — it mates directly with 2.5V or 3.3V logic families without a level shifter.

Housed in a 6-SMD no-lead package measuring 7.0 x 5.0 mm with a seated height of 0.9 mm — a standard footprint that fits most 100 MHz oscillator pads without a layout change.

No stock-holding claim — availability confirmed at RFQ.

Frequently asked questions

Can DSC1121AI5-100.0000T replace a standard quartz oscillator?

Yes — it is a drop-in replacement for a standard 100 MHz quartz XO in the same 7.0 x 5.0 mm 6-SMD footprint, with the added benefit of MEMS shock/vibration tolerance and faster startup.
