Product details

MEMS clock source for automotive and industrial timing

AEC-Q100 qualification means this oscillator is validated for automotive-grade reliability—suitable for engine control units, ADAS sensor interfaces, and infotainment clock trees where quartz shock and vibration sensitivity are a concern.

Supply voltage flexibility and enable/disable control

The 2.25V to 3.6V supply range allows direct connection to 2.5V or 3.3V rails without an external regulator—a single BOM line covers both logic families. An integrated Enable/Disable function lets the system shut down the oscillator when the clock is not needed. Maximum supply current is 35 mA when enabled, dropping to 22 mA when disabled—useful for power-sensitive modules that sleep between wake cycles.

Package footprint 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, the DSC1121AI2-065.5360T fits standard oscillator footprints and reflow profiles used for quartz XOs—no layout change needed when migrating from a crystal-based source.

Frequently asked questions

Can DSC1121AI2-065.5360T operate at 3.3V?

Yes. The supply voltage range is 2.25V to 3.6V, so a 3.3V rail is within the operating envelope. The CMOS output swing tracks the supply voltage, making it directly compatible with 3.3V logic families.

What is the closest pin-compatible alternative to DSC1121AI2-065.5360T in this Crystals & Oscillators family?

Within the DSC1121 series, other frequency variants share the same 6-SMD package, supply range, and pinout—only the output frequency changes. For a different frequency at the same stability and temperature grade, select the corresponding DSC1121AI2-xxxxxxT order code. No second-source MEMS oscillator is listed as a direct cross-reference.
