NCS1S1205SC - Murata Electronics

NCS1S1205SC Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for the NCS1S1205SC?
  Murata recommends a symmetrical layout with the oscillator placed at the center, and the output traces should be routed away from the oscillator to minimize noise coupling. A ground plane under the oscillator is also recommended to reduce electromagnetic interference.
• How do I ensure the NCS1S1205SC oscillator starts up reliably?
  To ensure reliable startup, Murata recommends applying power to the oscillator slowly (dV/dt < 10V/ms) and ensuring that the power supply voltage is stable before enabling the oscillator. Additionally, a 10nF to 100nF capacitor can be placed between the VDD and GND pins to filter out noise.
• What is the maximum frequency deviation of the NCS1S1205SC over temperature?
  The maximum frequency deviation of the NCS1S1205SC over the operating temperature range of -40°C to 85°C is ±100 ppm.
• Can I use the NCS1S1205SC in a harsh environment?
  The NCS1S1205SC is rated for operation in a temperature range of -40°C to 85°C, but it can be used in harsh environments with proper packaging and sealing. However, it's recommended to consult with Murata's application engineers for specific guidance on using the oscillator in extreme environments.
• How do I troubleshoot issues with the NCS1S1205SC oscillator?
  To troubleshoot issues with the NCS1S1205SC, check the power supply voltage, ensure the oscillator is properly connected, and verify that the output is not loaded excessively. Also, check for noise coupling and electromagnetic interference, and ensure the PCB layout is symmetrical and well-grounded.
