±0.5 ppm Super-TCXO for GNSS/GPS
The SiT5155 Super-TCXO is engineered for high-accuracy GNSS systems in precision farming, survey, construction, and other industrial equipment. Based on SiTime’s unique DualMEMS™ and TurboCompensation™ temperature sensing technology, this device delivers exceptional dynamic performance that enables the fastest lock to satellites in the presence of shock, vibration, rapid temperature change, power supply noise, and electromagnetic interference (EMI). The SiT5155 further minimizes the loss of satellite lock by eliminating activity dips and micro jumps.
