Abracon recommends following the recommended PCB layout guidelines in the datasheet, including using a solid ground plane, minimizing trace lengths, and avoiding vias under the oscillator. Additionally, it's recommended to use a 4-layer PCB with a dedicated power plane and a solid ground plane.
To ensure proper soldering, Abracon recommends using a soldering iron with a temperature range of 250°C to 260°C, and a solder with a melting point of 180°C to 220°C. The oscillator should be soldered in a way that minimizes mechanical stress and ensures good thermal conductivity.
Abracon recommends using a 10uF to 22uF ceramic capacitor in parallel with a 100nF to 220nF ceramic capacitor, placed as close as possible to the oscillator's power pins. This helps to filter out noise and ensure stable operation.
The AST3TDA53TACJ2-20.0000MHZ oscillator is designed to start oscillating within 5ms of power-up, and to stop oscillating within 1ms of power-down. The oscillator's output is high-impedance during power-down, and it's recommended to use a pull-down resistor to ensure a clean shutdown.
The AST3TDA53TACJ2-20.0000MHZ oscillator is designed to be resistant to EMI and RFI, but it's still recommended to take precautions such as using a metal shield, keeping the oscillator away from high-frequency sources, and using a low-pass filter on the output.
