The SiT8209 is a high-frequency, high-performance oscillator for telecom, networking, storage and wireless applications. It is the industry's first MEMS oscillator to deliver 500 femtoseconds of typical integrated RMS phase jitter (12 kHz to 20 MHz) and ±10 ppm frequency stability across all temperature ranges. This device has a rich set of configurable features, such as any frequency from 80 to 220 MHz and is available with extremely short lead time to ensure the fast time-to-market. With FlexEdge™ technology for EMI reduction, the SiT8209 improves system performance. The SiT8209 is footprint compatible with legacy quartz, SAW and overtone oscillators and can replace these devices without any board changes.

Configurable FlexEdge drive strength reduces EMI by slowing rise/fall time – for example the 11th clock harmonic is reduced by 35 dB by increasing the rise/fall edge from 5% to 45% of the period
