Product details

40 MHz MEMS oscillator for harsh-environment clocking

The DSC1101DM2-040.0000T is a MEMS-based XO (Standard) from Microchip's DSC1101 series, delivering a 40 MHz CMOS clock with ±25ppm frequency stability across the full -55°C to 125°C military temperature range.

Wide supply and standby power for system-level flexibility

The 2.25V to 3.6V supply range covers common logic rails (2.5V, 3.3V) and allows the oscillator to run directly from a battery or a loosely regulated bus without an extra LDO.

The 6-VDFN package measures 2.50mm x 2.00mm with a seated height of 0.90mm — a compact footprint for dense PCB layouts.

Frequently asked questions

Where can I buy DSC1101DM2-040.0000T and what is the lead time?

DSC1101DM2-040.0000T is an active Microchip part and can be sourced through independent distribution. No stock-holding claim is made; lead time depends on the lot size and date-code requirements.

Is DSC1101DM2-040.0000T a direct replacement for DSC1101CM2-040.0000?

The order codes differ in the temperature-grade suffix. They share the same 40 MHz frequency, CMOS output, and 6-VDFN package, but the 'DM2' is the wide-temperature version. Confirm the BOM's required temperature range before substituting.

What package size is DSC1101DM2-040.0000T?

The 6-VDFN package has body dimensions of 2.50mm x 2.00mm and a seated height of 0.90mm. It is a surface-mount package with a 0.50mm pitch — typical for a 6-pin VDFN. The land pattern should follow the Microchip recommended footprint for this package.
