Product details

MEMS oscillator for harsh environment timing

The DSC1121DM2-002.3000T is a MEMS-based XO (standard) oscillator from Microchip's DSC1121 series, delivering a 2.3 MHz CMOS output with ±25 ppm frequency stability over the full -55°C to 125°C military temperature range. AEC-Q100 qualification confirms this part meets automotive-grade stress and reliability requirements, suitable for under-hood ECUs, chassis control modules, or any application where the oscillator sees temperature cycling and vibration.

Runs from 2.25V to 3.6V, covering 2.5V and 3.3V logic rails without an external regulator. The 6-SMD no-lead package measures 2.50 mm x 2.00 mm with a seated height of 0.90 mm — a compact footprint that fits dense PCB layouts.

Frequently asked questions

Is DSC1121DM2-002.3000T AEC-Q100 qualified?

Yes, it carries AEC-Q100 ratings, which means it has passed automotive-grade reliability stress tests including temperature cycling, ESD, and latch-up. Suitable for under-hood and chassis-mounted electronics.

What is the exact frequency of this oscillator?

The output frequency is 2.3 MHz, with a CMOS output and ±25 ppm frequency stability over the full -55°C to 125°C range.

What is the difference between DSC1121 and DSC1122?

Both are MEMS oscillators from Microchip's DSC11xx family, but the DSC1121 series is a standard XO with a CMOS output, while the DSC1122 typically offers a different output type (LVDS or HCSL). The DSC1121DM2-002.3000T specifically is a standard XO with CMOS output — confirm the output type needed for your application.
