Product details

74.25 MHz MEMS clock for automotive and industrial timing

AEC-Q100 qualification means this part is validated for automotive-grade reliability, suitable for under-hood and chassis-domain applications where vibration and temperature cycling are routine. The Enable/Disable function lets the output be tri-stated (22 mA max supply in disable) for power-down or test modes without cycling the main supply rail.

Supply voltage and package fit for BOM planning

Operating from 2.25V to 3.6V, this oscillator covers 2.5V and 3.3V logic rails directly — no extra LDO needed in the clock tree. Housed in a 6-SMD, No Lead package measuring 3.20mm x 2.50mm with a seated height of 0.90mm, it fits tight PCB layouts common in automotive ECUs and industrial controllers. Maximum supply current is 35 mA during active operation, a figure to budget in the power rail design for multi-oscillator arrays.

Frequently asked questions

What is the frequency of the DSC1121CI2-074.2500?

The output frequency is 74.25 MHz, a common clock rate for video and networking applications.

Is the DSC1121CI2-074.2500 AEC-Q100 qualified?
