Why this MEMS XO over a quartz oscillator
At 4.096 MHz, this oscillator is a natural fit for UART baud-rate generation (e.g., 115200 baud from a 4.096 MHz clock) or as a base clock for audio sample-rate converters.
The 1.7V to 3.6V supply span lets it run from a 1.8V or 3.3V rail without an external level translator — the CMOS output swings rail-to-rail, so the downstream logic sees a clean square wave across the full voltage range.
Temperature grade and automotive qualification
The AEC-Q100 rating means the part passed the automotive stress tests (preconditioning, temperature cycling, HAST, high-temperature storage) and is PPAP-ready for production vehicle builds.
Housed in a 4-VDFN package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm — this is a standard MEMS oscillator footprint that lands on the same PCB pads as many quartz XO packages, so a layout swap is often a BOM change only.
