AB308-5.5296MHZ-18 - ABRACON

AB308-5.5296MHZ-18 Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal performance?
  Abracon recommends a symmetrical PCB layout with a solid ground plane, and keeping the oscillator away from high-frequency signals and noise sources. A minimum of 2-layer PCB is recommended, with the oscillator on the top layer and the ground plane on the bottom layer.
• How do I handle the oscillator's power supply noise sensitivity?
  To minimize power supply noise sensitivity, Abracon recommends using a low-dropout regulator (LDO) with a high power supply rejection ratio (PSRR) and a low equivalent series resistance (ESR) capacitor. Additionally, decoupling capacitors should be placed close to the oscillator's power pins.
• What is the maximum allowable frequency deviation for this oscillator?
  The maximum allowable frequency deviation for the AB308-5.5296MHZ-18 is ±50 ppm over the operating temperature range of -20°C to +70°C. This deviation is due to the crystal's natural frequency variation and can be affected by factors such as temperature, aging, and vibration.
• How do I ensure the oscillator's start-up time meets my system requirements?
  The start-up time of the AB308-5.5296MHZ-18 is typically around 2-5 ms. To ensure the oscillator meets your system requirements, Abracon recommends using a power-on reset (POR) circuit or a delay timer to allow the oscillator to stabilize before enabling the system clock.
• What is the recommended storage temperature range for this oscillator?
  Abracon recommends storing the AB308-5.5296MHZ-18 oscillator in a dry, non-conductive environment at a temperature range of -40°C to +125°C. Storage outside of this range may affect the oscillator's performance and reliability.
