Product details

It is AEC-Q100 qualified, making it suitable for automotive electronics such as engine control units, ADAS sensors, and infotainment modules where the oscillator must survive thermal cycling and vibration without frequency drift. The MEMS resonator inherently resists mechanical shock better than quartz — relevant for under-hood or chassis-mounted ECUs that see continuous vibration.

Operating from 1.8V to 3.3V, this oscillator can be powered directly from a 1.8V core rail, a 2.5V I/O rail, or a 3.3V peripheral bus — no separate LDO needed for the clock source.

Package, footprint, and tape-and-reel delivery

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 DSC1001AI2-012.2880T occupies a standard 7x5 mm oscillator footprint compatible with common quartz XO layouts.

Frequently asked questions

Is DSC1001AI2-012.2880T AEC-Q100 qualified?

Yes, it is AEC-Q100 qualified, which means it has passed automotive-grade reliability testing including temperature cycling, ESD, and latch-up.

Does DSC1001AI2-012.2880T require a load capacitor?

No. As a MEMS-based oscillator (not a quartz crystal), the DSC1001AI2-012.2880T generates a complete CMOS clock output and does not require external load capacitors or feedback resistors. The output is a rail-to-rail CMOS signal ready to drive a digital input.

What is the difference between DSC1001AI2-012.2880T and DSC1001AI2-012.2880?

The 'T' suffix indicates Tape & Reel packaging. DSC1001AI2-012.2880T is supplied on Tape & Reel for automated assembly; DSC1001AI2-012.2880 (without the T) is typically supplied in bulk or cut tape. The electrical specifications and footprint are identical.
