Endura Super-TCXO Delivers 100x Higher System Reliability for Aerospace and Defense

18/08/2023

New member to the field-proven Endura™ MEMS ruggedized Super-TCXO® family—the SiT5543. This temperature-controlled oscillator redefines the TCXO landscape for aerospace and defense systems with unmatched stability in challenging environments. SiTime’s new, ruggedized SiT5543 Super-TCXO offers an unprecedented ±5 ppb frequency stability over temperature from -40 °C to 95 °C, even during fast temperature transients and under vibration. The SiT5543 delivers an impressive 20x improvement in stability over existing open-market, quartz-based TCXOs, which are unable to provide stability better than ±100 ppb.

  • MEMS-based SiT5543 Super-TCXO delivers 100x higher reliability, 2x power reduction and 40% smaller size compared to OCXOs and 20x better stability than conventional TCXOs
  • Enables faster, low-latency data transmission and reductions in bit error rates in dynamic environments
  • Eliminates the need for costly, bulky, custom-made OCXOs, which are highly sensitive to acceleration, shock, and vibration

Main Features

  • 1 to 60 MHz programmable output frequency
  • ±5 ppb stability over -40 °C to +95 °C temperature range
  • ±0.3 ppb/°C stability over temperature slope
  • 0.01 ppb/g acceleration sensitivity
  • 0.5 ppb/day daily aging
  • Low ±150 ppb aging over 20 years, eliminating the need for system-level aging compensation
  • 2 seconds to final stability over temperature
  • Optional ±3200 ppm digital control with I2C
  • 20,000 g shock survivability
  • 110 mW typ. power consumption at 2.5V supply
  • 2.5 to 3.3V supply
  • 7.0 mm x 5.0 mm ceramic surface-mount package
