Product details

The MEMS die is sealed in a 5.00 mm x 3.20 mm 4-SMD no-lead package and delivers CMOS output with ±50 ppm frequency stability across the full -20°C to 70°C operating range. For engine-bay or exhaust-adjacent positions, a -40°C to 125°C rated variant from the same DSC1001 family would be required.

Supply range and power-down function

Supply voltage spans 1.8V to 3.3V, covering 1.8V, 2.5V, and 3.3V logic rails without an intermediate regulator — the same BOM line works across a multi-voltage design. The CMOS output drives standard logic inputs directly; no external termination or load resistor is needed for a single-ended clock tree.

Frequently asked questions

Can the DSC1001BE1 replace a standard quartz oscillator?

Yes, in most applications. The DSC1001BE1-027.0000T is a MEMS-based oscillator that is pin-compatible with standard 5.0 x 3.2 mm quartz XO footprints (4-SMD no-lead). The CMOS output and ±50 ppm stability match typical quartz performance, while the MEMS construction offers better shock and vibration immunity per Microchip's reliability data. The supply range (1.8V-3.3V) covers the common logic rails. No board spin is required for a drop-in replacement.

Is the DSC1001BE1-027.0000T suitable for automotive applications?

Yes, for cabin or infotainment domains. The oscillator is AEC-Q100 qualified, which means it has passed automotive-grade reliability stress and PPAP requirements. However, the operating temperature range is -20°C to 70°C — this limits deployment to interior or climate-controlled zones. For under-hood or engine-bay positions requiring -40°C to 125°C, a different temperature-grade variant from the DSC1001 family is needed.
