14.3181 MHz MEMS oscillator with AEC-Q100 qualification
The DSC1001CI2-014.3181: This is a 14.3181 MHz MEMS-based XO (Standard) oscillator from Microchip's DSC1001 series, delivering a CMOS output in a 4-SMD, no-lead package. The AEC-Q100 rating means this part has passed automotive-grade reliability stress tests: it belongs in under-hood ECUs, cabin infotainment, and chassis-domain modules where a standard crystal oscillator would risk drift or failure.
Supply flexibility and standby power-down
Accepts a 1.8V to 3.3V supply rail — one BOM line serves designs at 1.8V, 2.5V, or 3.3V without a separate regulator for the oscillator. The standby (power-down) function drops supply current to 15 µA max, letting the system shut the oscillator off between active cycles — useful in battery-backed or sleep-mode applications. Active current draw is 6.3 mA max at full speed — the MEMS resonator consumes less than a comparable quartz oscillator, which helps keep the thermal budget tight in dense boards.
Active production — no obsolescence pressure
The base product number DSC1001 covers a family of frequencies and stability grades; the CI2 suffix pins down the 14.3181 MHz variant with ±25 ppm stability in the 3.2 x 2.5 mm package.
