CSTCR4M91G53-R0 - Murata Electronics

CSTCR4M91G53-R0 Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal performance?
  A symmetrical layout with a ground plane underneath the oscillator is recommended. Keep the oscillator away from noise sources and ensure a low-impedance path to ground.
• How do I handle the oscillator's start-up time?
  The start-up time is typically around 2-3 ms. Ensure that your system design can accommodate this delay before the oscillator is stable and providing a reliable clock signal.
• What is the effect of temperature on the oscillator's frequency stability?
  The CSTCR4M91G53-R0 has a specified frequency stability of ±20 ppm over the operating temperature range of -40°C to 85°C. This means that the oscillator's frequency may vary by up to ±20 ppm over this temperature range.
• Can I use this oscillator in a high-vibration environment?
  The CSTCR4M91G53-R0 is designed to withstand vibrations up to 10 G. However, it's essential to ensure that the oscillator is properly mounted and secured to the PCB to prevent damage or frequency instability.
• How do I troubleshoot issues with the oscillator's output signal?
  Use an oscilloscope to verify the output signal's frequency, amplitude, and waveform. Check for proper power supply decoupling, ensure the oscillator is properly terminated, and verify that the load capacitance is within the recommended range.
