Product details

Active production, AEC-Q100 qualified

The DSC1001AI2-033.3333: Rated AEC-Q100, this oscillator meets automotive-grade qualification for reliability under temperature and stress conditions typical of under-hood or cabin electronics.

33.3333 MHz CMOS output with standby

Delivers a 33.3333 MHz CMOS output from a MEMS-based resonator, eliminating the quartz crystal's mechanical fragility and long lead-time risk.

Wide supply, small SMD footprint

Operates from 1.8 V to 3.3 V, covering the common core and I/O rails without a separate level translator — the same BOM line works across a 1.8 V MCU and a 3.3 V FPGA bank. Housed in a 4-SMD, no-lead exposed-pad package measuring 7.00 mm x 5.00 mm, the DSC1001AI2-033.3333 sits on a standard 7050 footprint with a 0.90 mm seated height.

Frequently asked questions

Is the DSC1001AI2-033.3333 AEC-Q100 qualified?

Yes, it carries an AEC-Q100 rating, making it suitable for automotive applications that require the reliability and temperature-grade qualification specified by that standard.

What is the output type and supply voltage range?

The output is CMOS, and the supply voltage range is 1.8 V to 3.3 V, allowing direct connection to common digital logic families without external level shifting.

What does the standby function do?

The standby (power-down) function disables the output and reduces current consumption to 15 µA max, useful for power gating the oscillator in low-power or sleep modes.
