Mining and Construction Equipment

Drilling rig and pile driver at construction site

Loaders, excavators, and drill equipment often operate in close proximity to blasts from explosives, subjecting them to shock and vibration that can adversely affect the electronics. SiTime MEMS timing solutions are nearly impervious to shock and vibration. They have proven 4x better vibration resistance and 20x better shock survivability compared to quartz crystal devices.

Mining and Construction Equipment Block Diagram

Factors besides shock and vibration, such as thermal and flicker noise can cause phase noise aberrations. Performance of wireless systems can be adversely affected with jitter and cause safety problems, especially if a wireless interface (WiFi or other) is being used to control and monitor remote equipment. Mitigating both phase noise and jitter is an important consideration and selecting the right components can alleviate costly design workarounds, save time and improve system performance and reliability. With a vibration resistance of 0.1 ppb/g (typical) and reliability of >2.2 billion hours MTBF, SiTime’s products are ideal for applications in harsh environments.
