72 MHz MEMS oscillator for automotive timing
The DSC1001CI2-072.0000T is a MEMS-based XO delivering a 72 MHz CMOS clock from a 1.8V to 3.3V supply rail — the wide voltage range lets it sit on the same 3.3V or 1.8V bus as the downstream logic without a separate regulator. AEC-Q100 qualification means this oscillator is characterized for automotive temperature and reliability stress — suitable for under-hood or cabin-domain ECUs where a standard quartz oscillator would need additional screening.
Standby function and power budget
The standby (power-down) function pulls the output to high-impedance and drops supply current to 15 µA max — useful for battery-backed modules that need to gate the clock during sleep without a separate enable buffer. Active draw is 8.7 mA max at 72 MHz; the MEMS resonator consumes less than a comparable quartz crystal oscillator at this frequency, which matters for thermally constrained enclosures.
Housed in a 4-SMD no-lead package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm — the 0.50 mm pitch lands are compatible with standard reflow profiles and the small footprint frees board space near the processor. Supplied on tape & reel for automated pick-and-place; the surface-mount profile matches JEDEC MSL-1 typical for MEMS oscillators, though the specific MSL level should be confirmed from the lot date code.
