125 MHz MEMS oscillator for automotive clock trees
AEC-Q100 qualification means this part has passed automotive-grade reliability stress — temperature cycling, ESD, and latch-up — making it suitable for cabin and chassis-domain electronics where the ambient stays below 85°C. The MEMS resonator replaces a quartz crystal, giving better shock and vibration tolerance and a faster start-up time compared to a traditional crystal oscillator.
Supply voltage and standby power-down
Supply voltage range is 1.8V to 3.3V, covering the common digital core and I/O rails — no external level translator needed when the oscillator feeds a 1.8V or 3.3V clock input. A standby (power-down) function drops the supply current to 15 µA max when the enable pin is de-asserted, letting the system gate the oscillator off during sleep modes without a separate load switch. Active current draw is 8.7 mA max at 125 MHz — the MEMS architecture keeps power low even at this frequency, which matters for thermally constrained automotive ECUs.
Package and board layout notes
Housed in a 4-SMD, No Lead Exposed Pad package measuring 7.00 mm x 5.00 mm with a seated height of 0.90 mm — the exposed pad on the underside should be soldered to a ground-plane thermal land for best thermal and electrical performance. Surface-mount assembly with standard reflow profiles; the MEMS die inside is less sensitive to reflow temperature gradients than quartz, but follow the recommended solder-land pattern in the datasheet.
