Elite Platform™ Super-TCXOs

SiTime's Elite Platform super-TCXOs  solve deep-rooted timing problems in telecom and networking equipment where they can enable the highest performance, best reliability, and the highest quality of service, even in the presence of environmental stressors. SiTime’s Elite timing solutions deliver 30 times better dynamic performance, ten times better dynamic stability, and 20 times better vibration resistance (g sensitivity).

Operating environments are becoming increasingly dense and less controlled, adding much-needed data capacity to carrier infrastructure. This densification requires timing references with higher dynamic performance to enable equipment to operate in high temperature, thermal shock, vibration, and unpredictable airflow. SiTime's Elite Platform solves long-standing timing problems by combining three essential elements of the Dual-MEMS™ architecture with TurboCompensation™: a TempFlat MEMS™ resonator, a MEMS temperature sensor, and a highly integrated mixed-signal IC. Elite Super-TCXOs support any frequency between 1 MHz to 220 MHz and offer unique features to deliver exceptional dynamic performance in the presence of common environmental hazards such as air flow, temperature perturbation, vibration, shock, power supply noise, and electromagnetic interference (EMI). They can be used to replace legacy quartz OCXOs in emerging 5G and IEEE 1588 synchronization applications while reducing power and size.

Features

  • ±100 ppb frequency stability from -40°C to +105°C, the wildest operating temperature available with any TCXO
  • 1 ppb/°C to 5 ppb/°C frequency slope (ΔF/ΔT) at an extremely fast temperature ramp rate of 10°C/minute, a performance level unique among timing devices
    • ppb/g vibration immunity, 20 times better than quartz TCXOs
  • No activity dips or micro-jumps eliminates costly inspection or burn-in test

  • 3e-11 Allan deviation (ADEV) at 10 second averaging time, 10 times better than quartz TCXOs
    • px/mv power supply noise rejection (PSNR), eliminates dedicated system LDO
  • Optional I2C/SPI tuning eliminates external DAC
