340 to 725 MHz, Ultra-Low Jitter, ±20 to ±50 ppm, I2C Programmable Oscillator

The Endura™ SiT3542 is a high-frequency, ultra-low jitter, user-programmable oscillator, engineered to deliver high reliability in aerospace and defense applications. This device utilizes SiTime's unique DualMEMS™ temperature sensing and TurboCompensation™ technology to deliver exceptional dynamic performance in harsh environments, making it:

  • 耐气流和热冲击
  • 耐机械冲击和振动
  • Robust against power supply noise

The device supports two in-system programming options:
1) Any-frequency mode to reprogram the clock output to any frequency between 1 MHz to 340 MHz
2)数字控制振荡器(DCO)模式转向或将时钟拉到±3200 ppm

Endura SiT3542 conforms to MIL-PRF-55310 and MIL-STD-883 specifications.
