SiTime Corporation’s SiT5357 series of ±100 ppb high-frequency MEMS precision super-TCXO device is engineered for high dynamic performance. It is fully compliant to the GR-1244 Stratum 3 oscillator specifications. By leveraging SiTime’s unique DualMEMS™ temperature sensing and TurboCompensation™ technology, the SiT5357 delivers the most stable timing in the presence of environmental stressors – airflow, temperature perturbation, vibration, shock, and electromagnetic interference (EMI). This device also integrates multiple on-chip regulators, providing power supply noise filtering and eliminating the need for a dedicated external LDO. SiT5357 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 costs associated with quartz TCXOs where each frequency is custom built. The SiT5357 delivers exceptional dynamic performance like resilience to environmental stressors such as shock, vibration, and fast temperature transients making it suitable for harsh environments.
