FXO-HC536R-27 datasheet by Fox Electronics

FXO-HC536R-27 Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal performance?
  Fox Electronics recommends a ground plane underneath the oscillator, with a minimum of 0.1 inch clearance around the device. A 0.01 μF decoupling capacitor between VCC and GND, placed close to the oscillator, is also recommended.
• How do I ensure the oscillator starts up reliably?
  To ensure reliable startup, Fox Electronics recommends applying power to the oscillator slowly, with a rise time of at least 1 ms. Additionally, the power supply should be well-regulated and free of noise.
• What is the maximum operating temperature range for this oscillator?
  The FXO-HC536R-27 is rated for operation from -40°C to +85°C. However, it's essential to note that the frequency stability and accuracy may degrade at extreme temperatures.
• Can I use this oscillator in a high-vibration environment?
  While the FXO-HC536R-27 is designed to be rugged, it's still susceptible to vibration-induced frequency shifts. Fox Electronics recommends using vibration-dampening materials or mounting the oscillator in a way that minimizes vibration transmission.
• How do I troubleshoot frequency drift or instability issues?
  To troubleshoot frequency drift or instability, Fox Electronics recommends checking the power supply voltage, ensuring proper PCB layout and decoupling, and verifying that the oscillator is operated within its specified temperature range.
