Abracon recommends following the recommended PCB layout guidelines in the datasheet, including using a ground plane, minimizing trace lengths, and avoiding vias under the oscillator. Additionally, it's recommended to use a 4-layer PCB with a dedicated ground layer to reduce noise and EMI.
To ensure reliable startup, Abracon recommends following the recommended power-up sequence, using a stable power supply, and ensuring the oscillator is properly decoupled. Additionally, it's recommended to add a 10-100nF capacitor in parallel with the oscillator to reduce startup time and improve reliability.
The AST3TQ-V-20.000MHZ-28 has an operating temperature range of -40°C to +85°C. However, it's recommended to derate the frequency tolerance and stability over temperature according to the datasheet specifications.
The AST3TQ-V-20.000MHZ-28 is designed to meet the requirements of MIL-STD-202G, Method 204D, Condition D, which includes vibration testing. However, it's recommended to consult with Abracon's application engineers to ensure the oscillator meets the specific vibration requirements of your application.
Abracon recommends following the recommended soldering profile in the datasheet, which includes a peak temperature of 260°C, a dwell time of 10-30 seconds, and a ramp rate of 3°C/second. It's also recommended to use a nitrogen atmosphere and to avoid using wave soldering or hot bar soldering.
