Hiding the MEMS resonators
The most revolutionary part of Sand 9's technology, is that when the teardowns start itemizing components inside these new mobile devices, they will not find the MEMS resonators anywhere in sight -- because Sand 9's MEMS resonators are in chip-scale packages that are over-molded inside the customer's package. In other words, instead of a metal can housing a quartz crystal oscillator, the MEMS equivalent will be located out-of-sight inside the chip package for which it is supplying the timing signals.
Sand 9's chip-scale design can be flipped and over-molded into the customer's own chip package, along with the chip for which it is providing the
