Suntsu Releases New Oscillators with Cutting Edge Silicon Technology

Unlike traditional oscillators, which derive their frequency from a mechanical resonator such as a quartz crystal or MEMS element, Suntsu’s resonator-free silicon oscillators generate the clock entirely from on-chip circuitry — delivering a highly reliable clock in harsh, high-vibration environments without any quartz or MEMS resonator [1] [2].

The built-in frequency synthesis and temperature sensor can generate frequency ranges from 10kHz to 350MHz with a frequency stability of +/-50ppm over -40 to 85°C while the LDO and filter circuit enhance the power supply noise suppression to achieve low jitter performance [3]. Because they derive frequency from on-chip circuitry rather than a mechanical resonator, silicon oscillators are inherently far less sensitive to vibration, shock, and EMI than crystal-based parts [1].

Due to their flexible frequency configuration and output logistics, these oscillators have relatively short production times which is critical for supply chain continuity.
