What is the possibility of fine tuning the frequency with a voltage? A “VCMO” would be desirable even if the final frequency would require a synthesizer post stage.


Sand 9’s MEMS technology can be used to make Voltage Controlled MEMS Oscillators (VCMOs). The VCMO would offer several advantages over quartz: e.g., low phase noise, high fundamental frequency, vibration immunity and package integration. The higher fundamental frequency would enable lower noise frequency synthesizers, benefiting performance-demanding applications. The high fundamental frequency is especially useful when paired with a Direct Digital Synthesis device, where high input frequency allows for higher output frequencies without the need for an input PLL.
