125 MHz MEMS oscillator for rugged environments
The DSC1101DM2-125.0000T is a MEMS-based XO delivering a 125 MHz CMOS output with ±25 ppm frequency stability across the full -55°C to 125°C military temperature range. A MEMS resonator replaces the quartz crystal, giving this oscillator better resistance to shock and vibration — relevant for avionics, downhole drilling, and satellite payloads where quartz can fail under sustained g-load.
Active production — no lifecycle risk
No official successor or cross-reference is published; the DSC1101 family covers this frequency and stability grade directly.
6-VDFN package — board layout notes
Housed in a 6-VDFN measuring 2.50mm x 2.00mm with a seated height of 0.90mm, this package fits tight-height enclosures but requires a well-designed solder stencil to avoid bridging on the centre pad. The Standby (Power Down) function pulls the output to high-impedance and drops supply current to 95 µA max — useful for battery-powered systems that gate the clock during sleep modes.
