SiTime oscillators are the smallest, high-performance programmable oscillator available and are suitable for use in high speed serial communications, consumer, portable, industrial, automotive and computation. This oscillator is packaged in standard low-cost plastic and chip-scale IC packages. System reliability is also increased with the SiT8102 by eliminating the quartz crystal and improved immunity to the environmental effects of vibration, shock, strain, and humidity.
