That puts it in the cabin and under-hood domain — a gearbox controller or a LiDAR processing board that sees 85°C ambient still has margin.
Supply voltage tolerance and current draw
The supply range spans 2.25V to 3.63V — a single 3.3V or 2.5V rail is fine, and the 1.38V window covers a 3.3V rail that droops under load without losing lock.
Housed in a 6-SMD, No Lead package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm. That is a standard 3.2 x 2.5 mm oscillator footprint — same land pattern as many quartz oscillators, so a board already laid out for a 3.2x2.5 mm can usually take this MEMS part without a layout spin. Surface-mount only; no through-hole option.
