Why a MEMS oscillator instead of a quartz can
The standby function (Power Down) drops supply current from 7.2 mA to 15 µA — useful in battery-backed or intermittently powered systems that wake the clock only when the bus is active.
Supply voltage flexibility and package footprint
A single supply range of 1.8V to 3.3V means this one oscillator can serve 1.8V, 2.5V, and 3.3V logic rails — a BOM simplification when the board has mixed-voltage domains. The 4-SMD no-lead package measures 2.50mm x 2.00mm with a seated height of 0.90mm — a compact footprint that fits tight layout areas, but the no-lead pads require a solder-paste stencil and reflow; hand-soldering is possible with careful iron work and a fine tip.
