Why choose a MEMS oscillator over quartz
The 1.71V to 3.63V supply range means this oscillator can run directly off a 1.8V or 3.3V rail without an intermediate regulator — handy when the MCU core and I/O banks are at different voltages. CMOS output swings rail-to-rail, so it drives standard digital inputs cleanly across the whole supply range.
Power budget and package footprint
That matters in a battery-backed ECU or a sensor node that runs 24/7. The 4-VLGA package is 2.5 mm x 2.0 mm with a seated height of 0.89 mm — it fits under a shield can or on a dense board where every square mm counts.
