153.6 MHz MEMS oscillator for automotive timing
AEC-Q100 qualification means this part is validated for automotive-grade reliability, suitable for under-hood and chassis-domain applications where vibration and thermal cycling are routine. The enable/disable function allows the output to be tri-stated, reducing supply current from 35mA to 22mA max when the clock is not needed — useful for power-sensitive ECU designs.
Supply voltage and output drive
Operating from a 2.25V to 3.6V supply rail, this oscillator can be powered directly from a 2.5V or 3.3V regulator without an external LDO, simplifying the power tree. CMOS output levels are compatible with most MCU and FPGA clock inputs; the 35mA max supply current at 153.6 MHz is typical for a high-frequency MEMS oscillator driving a moderate capacitive load.
Housed in a 6-SMD no-lead package measuring 5.00mm x 3.20mm with a seated height of 0.90mm, the DSC1121BI2-153.6000 fits standard oscillator footprints and reflow profiles for surface-mount assembly. The MEMS base resonator eliminates the quartz crystal's startup and aging concerns — no external load capacitors are needed, and the oscillator starts within microseconds of power being applied.
