27 MHz MEMS oscillator with full military temperature range
The DSC1101BM2-027.0000T is a 27 MHz XO (Standard) from Microchip's DSC1101 series, built on a MEMS resonator rather than a quartz crystal. The -55°C to 125°C rating is a military-temperature-grade specification — this oscillator can be deployed in avionics, satellite, downhole drilling, and missile-guidance systems where standard quartz oscillators would fail from thermal stress or vibration.
Supply voltage and power-down standby
Operating from a 2.25V to 3.6V supply, the part draws 35 mA maximum in active mode. The Standby (Power Down) function reduces supply current to 95 µA max, allowing the oscillator to be gated off in low-power system states without removing the supply rail.
Active lifecycle — no end-of-life risk
No successor or last-time-buy has been announced.
