Product details

MEMS oscillator at 2.3 MHz with AEC-Q100 grade

The DSC1121DM2-002.3000 is a MEMS-based XO (Standard) oscillator from Microchip's DSC1121 series, delivering a fixed 2.3 MHz CMOS output. The wide supply range of 2.25V to 3.6V lets it run off a 2.5V or 3.3V rail without a separate LDO. That matters for battery-backed RTC or sleep-mode power budgets.

Microchip lists the DSC1121DM2-002.3000 as Active.

Housed in a 6-SMD, No Lead package measuring 2.50 mm x 2.00 mm with a seated height of 0.90 mm. The 0.098" x 0.079" footprint is common across the DSC1121 family — the same land pattern serves multiple frequencies, so a last-minute frequency change doesn't force a board spin.

Frequently asked questions

What is the exact frequency of DSC1121DM2-002.3000?

The exact output frequency is 2.3 MHz. The part number suffix "-002.3000" encodes this frequency.

Is DSC1121DM2-002.3000 AEC-Q100 qualified?

Yes, it carries AEC-Q100 ratings, which means it has passed automotive-grade reliability stress tests and is suitable for use in vehicle electronics.

Does DSC1121DM2-002.3000 have an enable/disable pin?

Yes, the function is Enable/Disable. When disabled, the supply current drops from 35 mA max to 22 mA max, allowing power gating in low-power states.
