CTS Corporation recommends a symmetrical PCB layout with a solid ground plane, and keeping the oscillator away from noise sources and high-frequency signals. A 4-layer PCB with a dedicated ground plane is ideal.
To ensure reliable startup, ensure the power supply is stable and within the recommended voltage range. Also, add a 10nF to 100nF capacitor between the VCC and GND pins to filter out noise and ensure a clean power supply.
The 742C163681JP oscillator is rated for operation from -40°C to +85°C. However, it's recommended to derate the frequency tolerance and stability specifications at extreme temperatures.
The 742C163681JP oscillator is designed to withstand moderate vibration levels. However, for high-vibration environments, it's recommended to use a more ruggedized oscillator or add additional mechanical support to the PCB.
Check the power supply voltage, ensure the oscillator is properly connected, and verify the PCB layout meets the recommended guidelines. Also, check for any noise or interference sources nearby that might be affecting the oscillator's operation.
