Product details

The DSC1001DE1-030.3779T is a 30.3779 MHz MEMS-based oscillator (XO) from Microchip Technology's DSC1001 series, delivering a CMOS output with ±50 ppm frequency stability across its -20°C to +70°C operating range.

The supply voltage range spans 1.8 V to 3.3 V, covering the common digital rails without a separate LDO — the oscillator draws 7.2 mA max when enabled.

Housed in a 4-SMD, no-lead package measuring 2.50 mm x 2.00 mm with a seated height of 0.90 mm, the DSC1001DE1-030.3779T fits tight board stacks — the 0.098" x 0.079" footprint is common to many MEMS oscillators, so the layout can often accept a second-source device without a board spin.

Frequently asked questions

Is DSC1001DE1-030.3779T AEC-Q100 qualified?

Yes, it carries AEC-Q100 ratings, meaning it has passed automotive-grade stress tests including temperature cycling, ESD, and latch-up — suitable for under-hood and cabin electronics where reliability is critical.

What is the closest pin-compatible alternative to DSC1001DE1-030.3779T?

Within the DSC1001 series, any device sharing the same 4-SMD footprint and supply range is pin-compatible — the base product number DSC1001 covers the family. For a different frequency, select the matching DSC1001 variant; the package and pinout are identical.
