Abracon recommends a 4-layer PCB with a solid ground plane on the bottom layer, and a separate power plane for the oscillator circuit. Additionally, keep the oscillator circuit as close to the crystal as possible, and use a low-impedance path for the crystal connections.
To ensure reliable startup, Abracon recommends applying power to the device with a slow rise time (typically 1-10 ms) and ensuring that the power supply is stable and noise-free. Additionally, the crystal should be properly matched to the oscillator circuit, and the PCB layout should be optimized for minimal noise and interference.
The AMJDDFJ-A11T is rated for operation from -40°C to +85°C, but Abracon recommends derating the frequency tolerance and stability over the full temperature range. Consult the datasheet for specific derating guidelines.
The AMJDDFJ-A11T is designed to operate with a 10 MHz crystal, but Abracon can provide custom devices for other frequencies. Contact Abracon's technical support for more information on custom frequency options.
To troubleshoot oscillator issues, check the power supply voltage, ensure the crystal is properly connected and matched to the oscillator circuit, and verify that the PCB layout is correct. Also, check for any noise or interference on the power or signal lines that could be affecting oscillator operation.
