This white paper is an update on SiTime MEMS oscillator technology in response to the Epson white paper “Comparison of Crystal Oscillator and Si-MEMS Oscillators.” The Epson white paper compares quartz oscillators with a SiTime MEMS oscillator that was released in 2011, and a Microchip oscillator that was released in the same timeframe. Since then, SiTime has made groundbreaking progress in MEMS, analog, and systems technologies.
SiTime MEMS oscillators surpassed quartz technology in performance in 2013, and since then, we have been delivering significant technical value to our customers. This white paper includes some performance data on the Epson SG-210*B, which was the Epson device highlighted in the original Epson white paper, but focuses more on high performance differential output oscillators: the SiTime SiT9501 and the Epson EG-2121, a high-performance Epson oscillator that is functionally similar to the SiT9501 but is significantly inferior in performance.
