The SiT5356 from SiTime Corporation is a ±100 ppb to ±250 ppb precision MEMS Super-TCXO, temperature-controlled oscillator. This device is engineered for the best 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 SiT5356 delivers the most stable timing in the presence of environmental stressors: airflow, temperature perturbation, vibration, shock, and electromagnetic interference (EMI). SiT5356 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. These devices also integrate multiple on-chip regulators, providing power supply noise filtering and eliminating the need for a dedicated external LDO.
