Product details

24.576 MHz with AEC-Q100 — why this MEMS oscillator fits automotive and industrial clocks

Its AEC-Q100 qualification means this part has passed automotive-grade stress tests — temperature cycling, ESD, and latch-up — making it suitable for under-hood and cabin electronics where a quartz oscillator might fail under vibration or thermal shock. The MEMS base resonator inherently resists shock and microphonics better than a quartz crystal, which matters for engine control units, ADAS cameras, and infotainment modules that see constant vibration.

New designs can commit to this part without worrying about a sudden obsolescence-driven board spin. No minimum order constraints beyond standard reel or tube multiples.

The oscillator operates from 2.25 V to 3.6 V, covering common 2.5 V and 3.3 V logic rails without an external LDO. This wide range also absorbs rail ripple up to 200 mV without losing lock. The enable/disable function lets a GPIO or power-management IC gate the clock output. When disabled, the supply current drops from 35 mA max to 22 mA max — useful for sleep-mode power budgets in battery-backed ECUs.

Frequently asked questions

Is the DSC1121AI2-024.5760 AEC-Q100 qualified?

Yes, it carries AEC-Q100 rating. That means it has passed automotive-grade reliability testing including temperature cycling, ESD, and latch-up — suitable for under-hood and cabin applications.

What does the enable/disable function do on this oscillator?

The enable/disable pin allows a logic signal to turn the output on or off. When disabled, the oscillator stops switching and supply current drops from 35 mA max to 22 mA max, saving power in sleep or standby modes.

What is the frequency stability of the DSC1121AI2-024.5760?

This is tight enough for most Ethernet, USB, and audio clocking applications without external trimming.
