CTS Corporation 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 trace lengths and avoid crossing signal lines.
To ensure reliable startup, CTS recommends using a high-quality crystal with a load capacitance of 18pF, and ensuring the oscillator circuit is properly biased. Additionally, the power supply should be stable and free of noise.
The 288T232R161A1 is rated for operation from -40°C to +85°C, but CTS recommends derating the component for extended operation above 70°C to ensure reliability.
While the 288T232R161A1 is designed to be rugged, CTS recommends additional mechanical support and vibration testing to ensure the component meets the specific requirements of the application.
CTS recommends using a spectrum analyzer to measure the oscillator frequency and amplitude, and checking the power supply and biasing of the oscillator circuit. Additionally, ensure the crystal is properly seated and the PCB layout is correct.
