Product details

It is part of Microchip's DSC1001 series, designed as a drop-in replacement for quartz oscillators but with the shock and vibration tolerance that MEMS silicon resonators bring to automotive and industrial environments.

Supply voltage and output flexibility

Housed in a 4-SMD, No Lead package measuring 2.50mm x 2.00mm with a seated height of 0.90mm max. The small footprint suits space-constrained automotive modules; the no-lead construction reduces parasitic inductance compared to a leaded package.

Frequently asked questions

Is DSC1001DI1-033.3300T equivalent to a standard quartz oscillator?

Functionally yes — it is a drop-in XO replacement with CMOS output at 33.33 MHz. The difference is the MEMS base resonator, which offers better shock and vibration tolerance than quartz. The pinout and footprint match standard 4-SMD oscillators, so no board spin is needed.

Can DSC1001DI1-033.3300T operate at 3.3V?

Yes, the supply voltage range is 1.8V to 3.3V, so 3.3V operation is within spec. The CMOS output swings rail-to-rail, matching 3.3V logic levels.

Is DSC1001DI1-033.3300T qualified for automotive?

Yes, it carries AEC-Q100 qualification, meaning it has passed automotive-grade reliability testing including temperature cycling, ESD, and latch-up.
