AK7DBF1-148.5000T2 - ABRACON

AK7DBF1-148.5000T2 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 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 ensure the oscillator starts up reliably in my design?
  To ensure reliable startup, Abracon recommends a power-up ramp time of at least 1ms, and a power supply voltage that reaches the minimum specified voltage (1.8V) before the oscillator is enabled. Additionally, a 10nF to 100nF decoupling capacitor should be placed close to the oscillator.
• What is the maximum operating temperature range for this oscillator?
  The AK7DBF1-148.5000T2 has an operating temperature range of -40°C to +85°C, but it's recommended to derate the frequency tolerance by ±0.05ppm/°C for temperatures above +70°C.
• Can I use this oscillator in a high-vibration environment?
  The AK7DBF1-148.5000T2 is designed to withstand vibrations up to 20G, but it's recommended to follow Abracon's vibration testing guidelines and to ensure the oscillator is properly mounted and secured to the PCB.
• What is the recommended soldering profile for this oscillator?
  Abracon recommends a soldering profile with a peak temperature of 260°C, and a dwell time above 240°C of 10-30 seconds. The oscillator should be soldered using a no-clean flux, and the PCB should be cleaned after soldering to prevent contamination.
