Precision Super-TCXOs

Precision Super-TCXOs

Precision Super-TCXOs™, based on the Elite Platform™, have exceptional dynamic performance and rich features. These precision devices, with output frequency from 1 to 220 MHz, are engineered to solve deep-rooted timing problems in telecom and networking applications. Based on SiTime’s innovative DualMEMS™ architecture with TurboCompensation™, these Super-TCXOs enable the highest performance, best reliability and the highest quality of service, even in the presence of common environmental harzards.

 

Key Features:

 

  • 30x better dynamic performance for macro cells, small cells, syncE and optical networks
  • 3e-11 Allan Deviation (ADEV)
  • 0.2 ps/mv PSNR, eliminating dedicated LDO
  • No activity dips or microjumps
  • 10x better dynamic stability, replacing OCXOs in IEEE 1588 applications
  • 1 to 5 ppb/°C frequency over temperature slope
  • -40°C to +105°C operation uniquely enables fan-less outdoor equipment
  • 20x greater vibration resistance ensures continuous system operation
  • Optional in-system programmability (ISP) that improves system BOM, multi-protocol support
