Product details

40 MHz MEMS oscillator — automotive-grade clock source

The DSC1001DE1-040.0000T is a MEMS-based XO (Standard) oscillator from Microchip's DSC1001 series, delivering a 40 MHz CMOS output with ±50 ppm frequency stability across its -20°C to 70°C operating range.

Wide supply range and low-power standby

Operating from a single 1.8V to 3.3V rail, the oscillator covers common logic voltage domains without a dedicated regulator — the supply current draw is 7.2 mA max during active oscillation.

Surface-mount footprint for dense PCB layouts

Housed in a 4-SMD, No Lead package measuring 2.50 mm × 2.00 mm with a seated height of 0.90 mm, the oscillator fits tight automotive ECU layouts where board real estate is at a premium.

Frequently asked questions

Is DSC1001DE1-040.0000T available via RFQ confirmation and what is the lead time?

We source this active-production part through independent distribution channels.

What is the closest pin-compatible alternative to DSC1001DE1-040.0000T?

Within the DSC1001 series, other frequency variants (e.g., 25 MHz, 50 MHz) share the same 4-SMD footprint, supply range, and AEC-Q100 rating. A direct frequency substitute would require a different order code; no single pin-compatible drop-in exists for 40 MHz.

Can I use DSC1001DE1-040.0000T in automotive applications?

Yes — it carries AEC-Q100 qualification. Capable is not qualified; this part has the documented reliability testing behind it. Confirm the specific grade level with Microchip if your OEM auditor requires PPAP.
