Product details

AEC-Q100 MEMS oscillator – what it changes on your board

The supply voltage range spans 1.8V to 3.3V, covering the common digital core and I/O rails. Maximum supply current is 7.2 mA, and the standby (power-down) function drops draw to 15 µA – useful for battery-backed RTC or sleep-mode circuits where the oscillator must be disabled without removing power.

The 4-SMD No Lead package measures 2.50 mm × 2.00 mm with a seated height of 0.90 mm. The small footprint suits space-constrained automotive modules like camera ECUs or BMS boards.

Frequently asked questions

Can DSC1001DI2-028.3750B be used with a 3.3V supply?

Yes, the supply voltage range is 1.8V to 3.3V. The CMOS output swings rail-to-rail, so at 3.3V the output high level is 3.3V, compatible with 3.3V logic families.

Is DSC1001DI2-028.3750B a direct replacement for a quartz oscillator?

Functionally yes – it is a drop-in XO with CMOS output, same 4-pin SMD footprint. The difference is the MEMS resonator inside, which offers better shock/vibration tolerance and typically faster startup than a quartz-based oscillator. No board spin is needed if the original quartz XO uses the same 2.5 mm × 2.0 mm 4-SMD package and supply voltage.
