Product details

50 MHz MEMS clock for automotive and industrial boards

AEC-Q100 qualification means this part has passed the automotive-grade reliability stress suite — temperature cycling, ESD, latch-up — making it suitable for engine-adjacent or cabin electronics where a quartz crystal's shock sensitivity is a known failure mode.

Supply range and enable/disable control

Operates from 2.25 V to 3.6 V, covering 2.5 V and 3.3 V logic rails without an external regulator. The enable/disable function lets a downstream MCU gate the clock — pulling the pin low drops supply current from 35 mA max to 22 mA max, useful in sleep-mode power budgets.

Frequently asked questions

Is the DSC1121BI2-050.0000T AEC-Q100 qualified?

Yes.

Does the DSC1121BI2-050.0000T have an enable/disable function?

Yes. The enable/disable pin allows the output to be tri-stated. When disabled, the maximum supply current drops from 35 mA to 22 mA.

What is the difference between MEMS and quartz oscillators for this part?

The DSC1121 series uses a MEMS resonator instead of a quartz crystal. MEMS oscillators are inherently more resistant to shock and vibration — a known advantage in automotive and industrial environments where quartz can fracture or exhibit frequency shifts under mechanical stress.

Is the DSC1121BI2-050.0000T compatible with 3.3 V supplies?

Yes. The supply voltage range is 2.25 V to 3.6 V, so 3.3 V is within the operating window. The CMOS output swings rail-to-rail, matching 3.3 V logic levels directly.
