TempFlat MEMS Technology
Until recently, all MEMS-based oscillators used complex compensation circuitry to stabilize the output frequency over temperature. SiTime’s TempFlat MEMS resonator technology is a revolutionary breakthrough that reduces the need for temperature compensation. With TempFlat MEMS, oscillator frequency stability is ±50 to ±100 PPM without temperature sensors and compensation circuitry. And in ±5 PPM TCXOs, only simple compensation circuitry is needed. In both cases, TempFlat technology simplifies the design of the analog CMOS circuits, which results in reduced system size, lower power consumption and lower cost.
SiTime’s 32 kHz families are the first generation of devices to employ TempFlat MEMS technology. Uncompensated TempFlat MEMS-based 32 kHz timing devices have frequency stability that is two times better than 32 kHz quartz crystals as shown in the graphic. Plus, SiTime’s TempFlat MEMS-based 32 KHz solutions consume much less power and board space compared to quartz-based timing devices.
Integrated Timing Functionality
SiTime's MEMS resonators are the first and only solutions that enable complete integration of timing within a semiconductor package. Because SiTime’s resonators are manufactured using the MEMS First process, they can be cost-effectively embedded with another SOC die inside a plastic package. This unique capability offers the benefits of increased system performance and reliability, simplified system design, and reduced technical support. SOC vendors who use SiTime's MEMS resonators can now provide a complete, highly-accurate embedded clocking solution without the need for any external timing components.
