SiT5359 Datasheet

The SiT5359 is ultra-precision MEMS Super-TCXO optimized for ±50 ppb stability from 0°C to 70°C. It supports ±100 ppb stability in a wider temperature range (down to -40°C and up to 105°C) and operates in 60 to 220 MHz frequency range. It is fully compliant with the GR-1244 Stratum 3 oscillator specifications. The SiT5359 is engineered for best dynamic performance, it is ideal for high-reliability telecom, wireless and networking, industrial, precision GNSS, and audio/video applications.

Leveraging SiTime’s unique DualMEMS™ temperature sensing and TurboCompensation™ technologies, the SiT5358 delivers the best dynamic performance for timing stability in the presence of environmental stressors such as airflow, 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.
