Product details

The DSC6003JL2B-032K768 is a MEMS-based XO (Standard) oscillator from Microchip's DSC60XXB series, delivering a fixed 32.768 kHz CMOS output — the standard real-time-clock frequency — from a 1.8V to 3.3V supply rail.

Supply voltage and output compatibility

Operates across 1.8V to 3.3V without a separate Vdd selection pin — the same BOM position works in a 1.8V MCU domain or a 3.3V peripheral rail, reducing unique line items.

Housed in a 4-VLGA package measuring 2.50 mm x 2.00 mm with a seated height of 0.89 mm — the land pattern is the same as a standard 2.5x2.0 mm XO footprint, so no layout change from a quartz oscillator of the same size. Surface-mount only; supplied in tube per the listed package option.

No direct pin-compatible second-source from another manufacturer is listed; the MEMS resonator and AEC-Q100 rating are the differentiators that justify the single-source BOM position.

Frequently asked questions

Is the DSC6003JL2B-032K768 AEC-Q100 qualified?

Yes, it carries AEC-Q100 ratings, which qualifies it for automotive-grade applications including under-hood and engine-bay temperature environments (-40 to +105°C,).

What is the difference between the DSC6003JL2B-032K768 and a standard quartz crystal oscillator?

This is a MEMS-based XO (Standard) — the resonator is a silicon MEMS structure, not a quartz crystal. The MEMS construction offers better shock and vibration tolerance compared to quartz, which is why the part carries AEC-Q100 qualification for automotive use. The electrical interface — CMOS output, 32.768 kHz frequency, 1.8-3.3V supply — is identical to a quartz oscillator of the same footprint.
