AOTA-B252008S4R7MT - ABRACON

AOTA-B252008S4R7MT 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 to keep 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 correctly?
  To ensure the oscillator starts up correctly, Abracon recommends applying power to the VDD pin first, followed by the enable pin (if applicable). The oscillator should be powered up in a monotonic sequence, with the voltage rising from 0V to the recommended operating voltage.
• What is the maximum operating temperature range for this oscillator?
  The AOTA-B252008S4R7MT oscillator is rated for operation from -40°C to +85°C. However, it's recommended to derate the frequency stability and output amplitude at extreme temperatures.
• Can I use this oscillator in a high-vibration environment?
  The AOTA-B252008S4R7MT oscillator is designed to meet the requirements of MIL-STD-883, Method 2007.1, which includes vibration testing. However, it's recommended to consult with Abracon's application engineers to ensure the oscillator meets the specific vibration requirements of your application.
• 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 of 10-30 seconds. The oscillator should be soldered using a no-clean or water-soluble flux, and should not be exposed to temperatures above 280°C.
