Operating from 2.25V to 3.6V, this oscillator spans 2.5V and 3.3V logic rails without an intermediate regulator — a single supply rail serves the entire clock domain.
Housed in a 6-SMD, No Lead Exposed Pad package measuring 7.00 mm x 5.00 mm with a seated height of 0.90 mm.
This makes it appropriate for under-hood and cabin-domain ECUs where a MEMS resonator's shock tolerance is an advantage over quartz.
