Product details

Why choose a MEMS oscillator over quartz for a 4 MHz clock

Housed in a 4-SMD, No Lead package measuring 0.098" × 0.079" (2.50 mm × 2.00 mm) with a seated height of 0.035" (0.90 mm). This is a standard 2.0 × 2.5 mm SMD footprint for MEMS oscillators — the pad layout matches the industry-common 4-pin configuration, so a board designed for a quartz oscillator in the same footprint can accept this part with no layout change.

Supply voltage range and design margin

No external regulator or level shifter is needed when moving between a 3.3 V MCU and a 1.8 V I/O bank — the same oscillator serves both domains.

Active lifecycle — sourcing for production and prototype

Microchip lists the DSC1001DE1-004.0000T as Active.

Frequently asked questions

Is the DSC1001DE1-004.0000T AEC-Q100 qualified?

Yes, the ratings include AEC-Q100 qualification. This means the oscillator has passed automotive-grade stress tests including temperature cycling, ESD, and early-life failure screening, making it suitable for under-hood or cabin electronics where quartz oscillators may fail under vibration.

Can the DSC1001DE1-004.0000T replace a standard 4 MHz quartz crystal oscillator?

Yes, if the board is designed for a 2.50 mm × 2.00 mm, 4-pin, CMOS-input oscillator. The MEMS resonator provides better shock and vibration immunity than quartz. The supply voltage range (1.8 V–3.3 V) covers 3.3 V and 2.5 V logic. Confirm that the output drive strength and rise/fall times match your downstream load — the CMOS output is a standard 15 pF drive.

What is the standby current consumption of the DSC1001DE1-004.0000T?

When the Standby (Power Down) function is active, the supply current is 15 µA max. In active mode, the supply current is 6.3 mA max at 4 MHz.
