Product details

16 MHz MEMS oscillator with full military temperature range

The DSC1121AM2-016.0000T is a 16 MHz MEMS-based XO (Standard) from Microchip's DSC1121 series, delivering CMOS output with ±25 ppm frequency stability across the full -55°C to 125°C range. AEC-Q100 qualified, this oscillator is suited for automotive under-hood ECUs, avionics, downhole instrumentation, and other environments where a quartz crystal's temperature drift or shock sensitivity would cause timing failures.

Wide supply range and low power for always-on systems

Operating from 2.25V to 3.6V, the oscillator covers 2.5V and 3.3V logic rails without an external regulator — the supply voltage tolerance absorbs rail ripple from a switching converter upstream.

Surface-mount footprint and board integration

Housed in a 6-SMD, No Lead Exposed Pad package measuring 7.00 mm x 5.00 mm with a seated height of 0.90 mm, the DSC1121AM2-016.0000T fits standard oscillator footprints and reflow profiles.

Frequently asked questions

Is the DSC1121AM2-016.0000T AEC-Q100 qualified?

Yes, the DSC1121AM2-016.0000T carries AEC-Q100 qualification, which means it has passed the automotive-grade reliability stress tests (temperature cycling, ESD, latch-up) and is PPAP-ready for tier-one ECU programs.

Can the DSC1121AM2-016.0000T replace a standard quartz oscillator?

Yes, the DSC1121AM2-016.0000T is a drop-in replacement for a 16 MHz quartz oscillator in the same 7.00 mm x 5.00 mm 6-SMD footprint. The MEMS resonator is inherently more shock- and vibration-tolerant than quartz, and the ±25 ppm stability across -55°C to 125°C exceeds the temperature-compensated performance of most quartz XOs in that range.
