Product details

MEMS oscillator for extreme-temperature clocking

The DSC1101CM5-050.0000T is a 50 MHz MEMS-based XO (Standard) from Microchip's DSC1101 series, delivering a CMOS output across a -55°C to 125°C military temperature range — a fit for avionics, downhole instrumentation, and satellite payloads where a quartz crystal would drift or fail under shock.

No pin-compatible direct replacement from Microchip has been published for this exact order code.

Wide supply range and standby function

Operates from 2.25V to 3.6V, covering 2.5V and 3.3V logic rails without an external regulator — the integrated standby (power-down) function drops supply current to 95µA max when the clock is gated.

6-SMD no-lead footprint

Housed in a 3.20mm x 2.50mm 6-SMD no-lead package, seated height 0.90mm max — the compact footprint suits space-constrained designs, but the no-lead terminations require a solder-paste stencil with good aperture alignment to avoid opens.

Frequently asked questions

What is the replacement for DSC1101CM5-050.0000T?

Microchip has not published an official successor for this exact order code. A functionally equivalent MEMS oscillator with the same 50 MHz, CMOS output, and -55°C to 125°C rating would require checking the current DSC11xx or DSC12xx series — but pin compatibility cannot be assumed without reviewing the respective datasheets.
