AST3TQ53-T-40.000MHZ-2-C - ABRACON

AST3TQ53-T-40.000MHZ-2-C Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal performance?
  Abracon recommends a symmetrical layout with the crystal oscillator placed near the center of the PCB, and the output traces should be routed away from the input traces to minimize noise coupling.
• How do I ensure the crystal oscillator starts up reliably in my design?
  To ensure reliable startup, Abracon recommends a power-up ramp time of 1ms or slower, and a power supply voltage that reaches the minimum specified operating voltage (1.8V) before the oscillator is enabled.
• What is the maximum allowable frequency deviation for this crystal oscillator?
  The maximum allowable frequency deviation for the AST3TQ53-T-40.000MHZ-2-C is ±50 ppm over the operating temperature range of -40°C to 85°C.
• Can I use this crystal oscillator in a harsh environment with high vibration or shock?
  The AST3TQ53-T-40.000MHZ-2-C is designed to withstand moderate vibration and shock, but for harsh environments, Abracon recommends using a more ruggedized version, such as the AST3TQ53-T-40.000MHZ-2-C-TR, which is designed for high-reliability applications.
• How do I handle ESD protection for this crystal oscillator?
  Abracon recommends using ESD protection devices, such as TVS diodes or ESD arrays, on the input and output pins of the crystal oscillator to prevent damage from electrostatic discharge.
