The SiT5503 is a Stratum 3E MEMS precision oscillator optimized for ±5 ppb stability from -40°C to 95°C. Engineered for exceptional dynamic performance, it is ideal for replacing larger and less robust quartz OCXOs. SiT5503 is uniquely positioned for high reliability telecom, edge networking, IEEE 1588 PTP, and optical transport applications. Leveraging SiTime’s unique DualMEMS® temperature sensing and TurboCompensation® technologies, the SiT5503 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. This device also integrates multiple on-chip regulators to filter power supply noise, eliminating the need for a dedicated external LDO.
SiTime Corporation is the leader in MEMS-based timing. Transforming the timing industry with configurable solutions that replace legacy quartz devices SiTime enables differentiation of products with the higher performance, smaller size, lower power and beter reliability.
