SiTime offers Endura high-performance differential oscillators for high reliability aerospace and defense applications. These ruggedized devices provide low jitter and power supply noise rejection (PSNR) in the presence of environmental hazards, such as shock, vibration, noisy power supply, and EMI.

• Low acceleration sensitivity, 0.1 ppb/g
• Low 0.21 ps RMS jitter (typ.) in small industry-standard packages
• ±10 ppm with better dynamic stability in harsh environmental conditions
• Precise frequency steering, digital tuning to ±5 ppt
• Any frequency from 1 MHz to 725 MHz with 6 decimal places of
