Product details

48 MHz MEMS oscillator with AEC-Q100 qualification

AEC-Q100 qualification means this oscillator is validated for automotive-grade reliability, suitable for under-hood and chassis-domain clocking where temperature cycling and vibration are factors.

Supply voltage and enable/disable control

The wide supply range of 2.25V to 3.6V lets the oscillator operate from common 2.5V or 3.3V rails without an external regulator, simplifying power distribution. An integrated Enable/Disable function allows the output to be tri-stated, reducing max supply current from 35 mA to 22 mA when the clock is not needed — useful for power-sensitive or test modes.

Package and mounting for board integration

Housed in a 6-SMD, No Lead Exposed Pad package measuring 7.00 mm x 5.00 mm with a seated height of 0.90 mm, the DSC1121AI2-048.0000 is a surface-mount oscillator that fits standard clock footprints. The MEMS base resonator provides inherent shock and vibration tolerance compared to quartz crystals, reducing startup reliability issues in harsh environments.
