Product details

MEMS oscillator with full military temperature range

The DSC1101DM1-007.3700T is a MEMS-based XO (Standard) oscillator from Microchip, delivering a 7.37 MHz CMOS output with ±50 ppm frequency stability across the full -55°C to 125°C military temperature range. This makes it suitable for avionics, downhole instrumentation, satellite subsystems, and other mission-critical applications where a quartz crystal would struggle with shock and vibration.

Supply voltage flexibility and standby function

Operating from 2.25V to 3.6V, this oscillator can run on a 2.5V or 3.3V rail without an external regulator. The standby (power-down) function pulls the supply current from a 35 mA maximum active draw down to 95 µA maximum when disabled, which is useful for battery-powered or duty-cycled systems that need to conserve power between active periods.

Frequently asked questions

Where can I buy the DSC1101DM1-007.3700T and what is the lead time?

This part is active and available to order. Submit an RFQ with your target quantity; we will confirm current pricing and lead time from our sourcing channels. No stock-holding is claimed — each order is quoted individually.

Is the DSC1101DM1-007.3700T compatible with a 2.5V supply?

Yes. The supply voltage range is 2.25V to 3.6V, so a 2.5V rail is well within the operating window.

What is the difference between the DSC1101 and DSC1121 series?

The DSC1121 series typically offers tighter frequency stability options (e.g., ±25 ppm) and may include additional output formats like LVPECL or LVDS, whereas the DSC1101 is a standard CMOS-output XO. For a pin-compatible alternative with higher stability, check the DSC1121 series — but confirm the output type and supply voltage match your design.
