78602/16C - Murata Electronics

78602/16C Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal performance?
  Murata recommends a 4-layer PCB with a solid ground plane and a separate power plane for the oscillator circuit. The layout should also minimize signal traces near the oscillator to reduce noise and ensure optimal performance.
• How do I ensure the oscillator starts up reliably?
  To ensure reliable startup, Murata recommends applying a power-on reset signal to the device, and ensuring that the power supply voltage is stable and within the recommended range before enabling the oscillator.
• What is the maximum operating temperature range for this device?
  While the datasheet specifies an operating temperature range of -40°C to +85°C, Murata recommends derating the device's performance at temperatures above +70°C to ensure reliable operation.
• Can I use this device in a high-vibration environment?
  Yes, the 78602/16C is designed to withstand vibrations up to 10G, but Murata recommends taking additional precautions such as securing the device with a suitable mounting method and ensuring the PCB is properly secured to the chassis.
• How do I troubleshoot issues with the oscillator circuit?
  Murata recommends using a spectrum analyzer to measure the oscillator's frequency and amplitude, and checking the power supply voltage and decoupling capacitors to ensure they are within the recommended specifications.
