Product details

Its AEC-Q100 qualification (cite:) makes it suitable for automotive electronics where reliability under temperature and vibration is mandatory — think infotainment clocking, camera modules, or ADAS sensor timing. Frequency stability is ±50ppm (cite:), adequate for most serial interfaces and MCU clocks, though not for precision RF or timekeeping. The 4-SMD no-lead package (3.20mm x 2.50mm) (cite:) fits standard oscillator footprints, but the narrow -20°C floor means it is not for cold-start engine bay or outdoor telecom without enclosure heating.

A standby (power-down) pin (cite:) drops the current draw to 15µA max (cite:) from 6.3mA max active (cite:). This is useful for battery-backed systems where the oscillator must sleep between wake cycles — the MEMS resonator restarts faster than a quartz crystal, so the first clock edge arrives sooner after power-up.

Product status is Active (cite:). The DSC1001 series (cite:) is Microchip's current MEMS oscillator family, so design-in for new projects carries no near-term obsolescence risk.

Frequently asked questions

Does the DSC1001CE1-014.3182T have AEC-Q100 qualification?

Yes, it is rated AEC-Q100 (cite:), which means it has passed automotive-grade stress tests including temperature cycling, ESD, and latch-up. This qualifies it for under-hood and cabin electronics where the ambient temperature stays within -20°C to 70°C.

Can the DSC1001CE1-014.3182T replace a standard 14.318 MHz crystal oscillator?

Yes, if the original design uses a CMOS-compatible XO with a 14.31818 MHz output. The MEMS resonator is more shock- and vibration-tolerant than quartz, and the supply voltage flexibility (1.8V-3.3V) (cite:) covers most logic families. However, the ±50ppm stability (cite:) may be looser than some precision quartz oscillators — check the target system's ppm budget before substitution.

What is the standby current when power-down is activated?

The supply current in disable (standby) mode is 15µA max (cite:). This is the current drawn when the output is disabled via the standby pin, not the leakage of the entire circuit.
