Product details

MEMS oscillator with automotive-grade reliability

The DSC1001AE1-033.3333 is a 33.3333 MHz MEMS-based XO (Standard) from Microchip's DSC1001 series, delivering a CMOS output with ±50 ppm frequency stability across its -20°C to +70°C operating range.

Operates from a 1.8V to 3.3V supply rail — the same part works across a 1.8V MCU core rail or a 3.3V peripheral bus without a separate voltage regulator.

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 — a standard footprint that reflows on a standard FR-4 board without via-in-pad.

Frequently asked questions

Can DSC1001AE1-033.3333 be used in automotive applications?

Yes — it carries AEC-Q100 qualification, meaning it has passed the automotive-grade reliability tests (temperature cycling, ESD, latch-up). It is suitable for under-hood or cabin ECUs that require a -20°C to +70°C operating range.

Can DSC1001AE1 replace standard quartz oscillators?

Yes — the MEMS resonator is a drop-in replacement for a quartz XO in the same 7.00 mm x 5.00 mm 4-pin footprint. No external load capacitors are needed, and the MEMS structure is more resistant to shock and vibration than a quartz crystal.
