What this MEMS oscillator does on the board
It operates from a 1.8V to 3.3V supply, so it can run off a 3.3V or 1.8V rail without a separate regulator, and draws 8.7 mA max — roughly half the current of a comparable quartz oscillator at this frequency.
Automotive-grade timing for harsh environments
Package fit and footprint
Housed in a 4-SMD, No Lead package measuring 5.00 mm x 3.20 mm with a seated height of 0.90 mm — this is the standard 5x3.2 mm oscillator footprint that matches many quartz XO pads, so a board laid out for a quartz oscillator can often take this MEMS part without a layout change.
