Product details

MEMS oscillator for industrial timing

A MEMS resonator replaces the quartz crystal — no aging drift, better shock/vibration tolerance, and a faster start-up than a comparable quartz oscillator. Supply voltage spans 2.25V to 3.6V, so it runs on a 3.3V or 2.5V rail without an extra regulator.

Active lifecycle — no design-in risk

Sourced through independent distribution; quoted to order against the BOM quantity. Availability confirmed at RFQ.

6-VDFN package and board fit

Enable/Disable pin lets a GPIO gate the output — the disable current drops to 22 mA max, useful for power-cycled or shared-clock buses.

Frequently asked questions

Can the DSC1121AL5-050.0000T operate at 3.3V?

Yes, the supply voltage range is 2.25V to 3.6V, so a 3.3V rail is within spec. The 50 MHz CMOS output swings rail-to-rail, so the logic levels match 3.3V CMOS inputs directly.
