SiTime’s MEMS oscillators have a substantially smaller mass, about 1000 to 3000 x smaller than quartz. Since it takes a large acceleration to move a small mass, SiTime’s MEMS oscillators have greater immunity to shock and vibration. Additionally, the design of the resonator is comparable to an extremely stiff spring that would require a very large force to make it move. SiTime’s MEMS oscillators require a force greater than 1 M g or 55,000 x the force of a Howitzer cannon before the resonator would touch any surface. SiTime oscillators do not require bulky packaging to compensate for shock and vibration because of the analog circuit design combined with the small MEMS resonator design (which is self-compensating). When sections of the resonator are moved in one direction, a different mechanism moves frequency in the opposite direction, cancelling each others’ effect. This results in minimal overall frequency deviation and superior performance compared to quartz and other MEMS oscillators.
