Low Jitter Oscillators

SiTime’s low jitter, ultra-performance oscillators for telecom, storage, networking, and wireless applications. These MEMS oscillators deliver 500 femtoseconds of typical integrated RMS phase jitter (12 kHz to 20 MHz) and ±10 ppm frequency stability across all temperature ranges. These parts support a rich set of configurable features, such as frequency, and FlexEdge™ EMI reduction technology, which improves system performance and ensures the fastest time-to-market. Many of these parts are footprint compatible with the legacy quartz devices. SiTime also offers fixed frequency differential oscillators which support LVPECL and LVDS output signaling types in different package options. The most recent products are based on SiTime’s unique Elite Platform™, which offers exceptional dynamic performance and stable timing in the presence of environmental hazards such as shock, vibration, power supply noise, and EMI.

By leveraging SiTime's unique DualMEMS temperature sensing and TurboCompensation technology, these oscillators offer the most stable timing in the presence of environmental stressors: air flow, temperature perturbation, vibration, shock, and electromagnetic interference (EMI). These devices also integrate multiple on-chip regulators, providing power supply noise filtering and eliminating the need for a dedicated external LDO. Low jitter oscillators can be factory-programmed to any combination of frequency, stability, voltage, and pull range. This programmability enables designers to optimize the clock configuration while eliminating the long lead time and customization cost associated with quartz TCXOs where each frequency is custom built.
