MEMS clock source for industrial temperature spans
Unlike a quartz crystal, the MEMS resonator is immune to vibration-induced frequency shifts and has no start-up reliability concerns — it simply powers up and outputs the clock.
Supply voltage range of 2.25V to 3.6V covers common 2.5V, 3.0V, and 3.3V rails without an external LDO — the oscillator runs directly off the core or I/O supply.
Housed in a 6-VDFN package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm, this is a low-profile, surface-mount part that fits tight vertical stacks in portable or embedded designs. The 6-VDFN has a small pad footprint and no exposed thermal pad — rework is straightforward with hot air, but the tiny package demands careful alignment and a clean stencil to avoid solder bridging under the body.
