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
