Product details

33.3333 MHz MEMS clock source with AEC-Q100 qualification

AEC-Q100 qualification means this part is screened for automotive-grade reliability — suited for under-hood or chassis-domain applications where a standard crystal oscillator would not carry the required stress testing.

Standby power-down and supply flexibility

The standby (power down) function drops the supply current to 15 µA max when disabled — useful in battery-backed or intermittently powered systems where the clock tree must be gated to conserve energy. Supply voltage range is 1.8V to 3.3V, covering common digital rails without an external level translator; the 7.2 mA max active current keeps the thermal load low in the 3.20mm x 2.50mm 4-SMD package.

Active production — no obsolescence pressure

Sourced through independent distribution; quoted to order against the BOM quantity.

Frequently asked questions

Can the DSC1001CI1-033.3333T replace a standard 33.3333 MHz crystal oscillator?

Yes, as a MEMS-based XO with CMOS output, it is a drop-in replacement for a standard crystal oscillator at the same frequency and output type. The AEC-Q100 qualification and wider supply voltage range (1.8V to 3.3V) give it additional capability that a basic oscillator may lack.
