DESCRIPTION
Leveraging SiTime’s unique DualMEMS® temperature sensing and TurboCompensation® technologies, the SiT5156 delivers the best dynamic performance for timing stability in the presence of environmental stressors such as air flow, temperature perturbation, vibration, shock, and electromagnetic interference. The SiT5156 offers three device configurations that can be ordered using Ordering Codes for: 1) TCXO with non-pullable output frequency, 2) VCTCXO allowing voltage control of output frequency, 3) DCTCXO enabling digital control of output frequency using an I2C interface, pullable to 5 ppt (parts per trillion) resolution. The SiT5156 can be factory programmed for any combination of frequency, stability, voltage, and pull range. Programmability enables designers to optimize clock configurations while eliminating long lead times and customization costs associated with quartz devices where each frequency is custom built. Refer to Manufacturing Guideline for proper reflow profile and PCB cleaning recommendations to ensure best performance.
