32.402 - Altech

32.402 Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal performance?
  Altech recommends a symmetrical PCB layout with a solid ground plane, and the oscillator should be placed as close as possible to the power supply. Additionally, the output should be routed away from the input to minimize feedback.
• How do I ensure the oscillator starts up reliably in my application?
  To ensure reliable startup, Altech recommends applying a clean power supply with minimal noise and ripple. The power supply voltage should be within the recommended range, and the oscillator should be decoupled with a 10nF to 100nF capacitor.
• What is the maximum frequency deviation over temperature?
  The 32.402 oscillator has a maximum frequency deviation of ±50 ppm over the operating temperature range of -40°C to +85°C.
• Can I use the 32.402 oscillator in a high-vibration environment?
  Yes, the 32.402 oscillator is designed to operate in high-vibration environments. However, it's essential to ensure the oscillator is properly mounted and secured to the PCB to prevent mechanical stress.
• How do I troubleshoot issues with the oscillator's output frequency?
  To troubleshoot issues with the oscillator's output frequency, check the power supply voltage, ensure the oscillator is properly decoupled, and verify the PCB layout is symmetrical and well-grounded. If issues persist, consult the datasheet or contact Altech's technical support.
