100 MHz MEMS XO for harsh environments
The DSC1121BM1-100.0000: That means this oscillator keeps a 100 MHz clock running in an engine bay at 125°C ambient or on a satellite bus at -55°C — environments where a quartz crystal would drift or stop. The MEMS resonator inherently handles higher shock and vibration than quartz, so the frequency stays locked under the G-loading you see in downhole drilling or missile guidance.
Automotive-grade reliability and supply flexibility
AEC-Q100 qualified, this part is production-ready for automotive ECU, ADAS camera, or radar module designs where the PPAP trace matters. The supply voltage range of 2.25V to 3.6V covers 2.5V and 3.3V rails without an external regulator — one less BOM line.
6-SMD footprint and layout fit
Housed in a 6-SMD, No Lead package measuring 5.00mm x 3.20mm with a seated height of 0.90mm.
