Product details

50 MHz MEMS oscillator with full military temperature range

The DSC1121AM2-050.0000T is a 50 MHz MEMS-based XO (Standard) oscillator from Microchip's DSC1121 series, delivering a CMOS output with ±25 ppm frequency stability across the full -55°C to +125°C military temperature range. The MEMS resonator eliminates quartz crystal startup delays and offers superior shock resistance compared to a standard quartz oscillator, a practical advantage in high-vibration environments like engine bays or avionics.

Operating from a 2.25V to 3.6V supply, this oscillator covers 2.5V and 3.3V logic rails without an external regulator — a single rail powers the device.

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 footprint is compatible with standard reflow soldering profiles.

Frequently asked questions

What are the exact specifications of the DSC1121AM2-050.0000T?

It is a 50 MHz XO (Standard) MEMS oscillator with CMOS output, ±25 ppm frequency stability, operating from 2.25V to 3.6V supply, over -55°C to +125°C. It is AEC-Q100 qualified, has an Enable/Disable function, and comes in a 6-SMD No Lead Exposed Pad package measuring 7.00 mm x 5.00 mm x 0.90 mm. Maximum supply current is 35 mA enabled, 22 mA disabled.

Is the DSC1121AM2-050.0000T suitable for automotive applications?

Yes. It is AEC-Q100 qualified, which means it has passed automotive-grade reliability testing including thermal cycling, ESD, and latch-up.

How does the DSC1121AM2-050.0000T compare to a standard quartz oscillator?

The MEMS resonator provides better shock and vibration immunity than quartz, and eliminates the quartz startup time — the oscillator is ready at power-on without a settling delay. The wide temperature range and AEC-Q100 qualification also exceed typical commercial quartz oscillator ratings.
