Ultra-low Power Fast Start OCXO

31/01/2025

Clocking solutions need to meet the requirements of fast start-up and battery life of portable battery-powered devices such as portable wireless communications devices, mobile test equipment-level mobile precision positioning, etc. while ensuring the performance and stability. However, the power consumption of OCXO has been a problem in such application scenarios all along.

In this context, Dapu breaks through the bottleneck of OCXO’s power consumption technology based on nearly two decades of accumulation of independent core technology in high-stability crystal oscillators. By adopting advanced vacuum holder structure and exclusive patented design solutions for precise temperature control of OCXO, Dapu fundamentally solves the issue of high-power consumption in ordinary OCXOs, while shortening the warm-up time to less than 60 seconds.

Main Features

  • Frequency Range: 9.6MHz ~ 100MHz
  • Power Supply Voltage: 3.3V / 5.0V
  • Stable Power Consumption: 100mW (Typ.)
  • Output Waveform: HCMOS / Sinewave
  • Temperature Stability: ±5 ppb
  • Phase Noise: -160 dBc/Hz@1KHz (Max.) @10MHz
  • Warm-up Time: 60s (Typ.)
  • Operating Temperature: -10°C ~ +60°C / -40°C ~ +85°C
  • Moisture Sensitivity Level: MSL1 (Industry’s First Airtight Design)
  • Package Size: 19.0 x 19.0 x 10.5mm
