ABLS-LR-14.7456MHZ-T - ABRACON

ABLS-LR-14.7456MHZ-T Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal performance?
  Abracon recommends a symmetrical PCB layout with a ground plane underneath the oscillator to minimize noise and radiation. A 4-layer PCB with a dedicated ground plane is ideal. Keep the oscillator away from high-frequency signals and ensure a clear return path for the ground connection.
• How do I ensure the oscillator starts up reliably in my design?
  To ensure reliable startup, Abracon recommends a power-up ramp time of at least 1 ms/V, a power supply voltage within the specified range, and a stable temperature environment. Additionally, ensure the oscillator is not subjected to excessive noise or EMI during startup.
• What is the maximum allowable frequency deviation for this oscillator?
  The ABLS-LR-14.7456MHZ-T has a frequency tolerance of ±20 ppm over the operating temperature range. This means the oscillator's frequency can deviate by up to ±294 Hz from the nominal frequency of 14.7456 MHz.
• Can I use this oscillator in a high-temperature environment?
  The ABLS-LR-14.7456MHZ-T is rated for operation up to 85°C. While it can tolerate short-term excursions up to 100°C, prolonged exposure above 85°C may affect the oscillator's performance and longevity. Consult Abracon for custom high-temperature options if needed.
• How do I handle the oscillator's output signal in my design?
  The ABLS-LR-14.7456MHZ-T has a CMOS output stage with a maximum output current of 10 mA. Ensure the output signal is properly terminated and matched to the load impedance to prevent signal reflections and ensure reliable operation.
