MEMS-based Silicon Oscillators All of SiTime's programmable, MEMS-based Silicon Oscillators are manufactured completely in Silicon, with no quartz crystals. A MEMS-based Silicon Oscillator combines a MEMS Resonator die with a Programmable Analog Semiconductor die and encapsulates both within a cost-effective, standard plastic package. in Public bookmarkswith oscillatorssiliconsilicon-oscillator
