SiTime Transforms Precision Timing Market for Edge Networks

01/04/2022

The Elite X™ Super-TCXO® for edge networks such as data centers, 5G front haul, connected cars and industrial IoT. In these applications, Elite X solves critical timing problems and enables delivery of new services.

The Elite X™ SiT5501 is a ±10 ppb Stratum 3E precision oscillator. Engineered for exceptional dynamic performance, this MEMS-based Super-TCXO is ideal for replacing larger and less robust quartz mini-OCXOs in edge networks. The SiT5501 is 2x smaller, 4x lower power, and 30x more reliable than comparable mini-OCXOs while being fully compliant to the GR-1244 Stratum 3E oscillator specifications.

Main Features

Exceptional dynamic stability under airflow, fast temp. ramp

  • ±10 ppb over-temp. stability from -40 to 105°C
  • ±0.5 ppb/°C frequency slope (ΔF/ΔT), 10°C/min ramp
  • Ensures system-level quality of service for telecom and networking equipment in hostile environments
  • ±0.5 ppb/day aging
  • 2e-11 ADEV at 10 second averaging time

4x lower power and 2x smaller for compact edge devices

  • 110 mW typical power consumption (2.5V)
  • Robust 7.0 mm x 5.0 mm package

20x better phase noise under vibration

  • Minimizes call and/or link drops in high-vibration environments

No activity dips or microjumps

  • Eliminates any need for costly screening or burn-in tests

0.2 ps/mV power supply noise rejection (PSNR)

  • Reduces BOM by eliminating a dedicated LDO for TCXO
