Product details

100 MHz MEMS oscillator for extreme-temperature clocks

The DSC1101CM5-100.0000 is a MEMS-based XO (Standard) oscillator delivering a 100 MHz CMOS output with ±10 ppm frequency stability across the full -55°C to 125°C military temperature range. That temperature grade is the key differentiator: most quartz oscillators drift or fail above 85°C, but this MEMS resonator holds frequency through the thermal extremes you see in avionics, downhole drilling, or satellite bus clocks. The supply voltage range spans 2.25V to 3.6V, so it runs directly off a 3.3V or 2.5V rail without an intermediate regulator.

Microchip lists the DSC1101CM5-100.0000 as obsolete. No last-time-buy window remains open.

The 6-SMD, no-lead package measures 3.20 mm x 2.50 mm with a seated height of 0.90 mm. That 0.126" x 0.098" footprint is common among MEMS oscillators in this frequency range, so a layout designed for a similar 6-pin MEMS XO should accept this part without a board spin.

Frequently asked questions

What is the replacement for DSC1101CM5-100.0000?

Microchip has not designated a direct pin-compatible replacement for the DSC1101CM5-100.0000. The DSC1101 series is obsolete, and no official successor part number is published. For a functionally equivalent 100 MHz MEMS oscillator with CMOS output and -55°C to 125°C range, you would need to evaluate current-generation MEMS oscillators from Microchip or other vendors, but a board layout review is required — pinout and footprint may differ.

Is DSC1101CM5-100.0000 compatible with 3.3V supply?

Yes. The supply voltage range is 2.25V to 3.6V, so 3.3V is well within the operating window. No external regulator is needed if your rail is within that range.

Does DSC1101CM5-100.0000 have a standby mode?

Yes, the function is listed as Standby (Power Down). When disabled, the supply current drops to 95 µA maximum, compared to 35 mA in active operation.
