MEMS oscillator with military temperature range
The MEMS resonator gives this oscillator inherent shock and vibration tolerance compared to quartz-based XOs, and the wide 2.25V to 3.6V supply range means it can be powered directly from a 2.5V or 3.3V rail without an intermediate LDO.
Temperature grade and deployment fit
Housed in a 6-VDFN package with exposed pad (7.00 mm × 5.00 mm, 0.90 mm seated height), the DSC1121AM1-029.4912T requires a thermal pad on the PCB for proper heat dissipation — the exposed pad should be connected to the ground plane with multiple vias. Surface-mount on Tape & Reel (TR), compatible with standard pick-and-place and reflow processes.
