CTS recommends a 4-layer PCB with a solid ground plane and a separate power plane to minimize noise and ensure optimal performance. Additionally, keep the signal traces as short as possible and avoid routing them near the crystal oscillator.
To ensure reliable startup, make sure the crystal oscillator circuit is properly biased, and the crystal is of high quality. Also, ensure the PCB layout is optimized for minimal noise and parasitic capacitance. If necessary, add a startup capacitor (typically 10-100 nF) in parallel with the crystal to aid startup.
The 206-9RAST is rated for operation from -40°C to +85°C. However, it's essential to note that the oscillator's frequency stability and accuracy may degrade at extreme temperatures. Consult the datasheet for specific temperature-related specifications.
While the 206-9RAST is designed to be rugged, it's still susceptible to vibration-induced frequency shifts. If your application involves high vibration, consider using a vibration-resistant oscillator or taking additional measures to secure the oscillator and PCB.
To troubleshoot frequency output issues, first verify the power supply voltage and ensure it's within the recommended range. Check the PCB layout for any noise or signal integrity issues. Use an oscilloscope to measure the oscillator's output frequency and verify it against the specified frequency. If issues persist, consult the datasheet or contact CTS Corporation's technical support.
