SiT5358 Precision MEMS Super-TCXOs

SiTime’s super-TCXOs are ideal for a variety of applications such as test and measurement and audio/video

Image of SiTime SiT5358 Precision MEMS Super-TCXOsLeveraging SiTime's unique DualMEMS™ temperature sensing and TurboCompensation™ technologies, the SiT5358 MEMS oscillators from SiTime Corporation deliver a dynamic performance for timing stability in the presence of environmental stressors such as air flow, temperature perturbation, vibration, shock, and electromagnetic interference. This device also integrates multiple on-chip regulators to filter power supply noise, eliminating the need for a dedicated external LDO.

Precision SiT5358 MEMS super-TCXO oscillators are optimized for ±50 ppb stability from 0°C to +70°C. They support ±100 ppb stability in a wider temperature range (down to -40°C and up to +105°C). SiT5358 oscillators are custom programmed by DigiKey to any combination of frequency, voltage, and pull range. This programmability enables designers to optimize the clock configuration while eliminating the long lead time and customization costs associated with quartz TCXOs where each frequency is custom-built. Engineered for best dynamic performance, it is ideal for high-reliability telecom, wireless and networking, industrial, precision GNSS, and audio/video applications.
