ARJ11B-MESBQ-A-B-EMU2 - ABRACON

ARJ11B-MESBQ-A-B-EMU2 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 4-layer PCB with a dedicated ground plane is ideal. Refer to Abracon's application note AN-04 for more details.
• How do I ensure the oscillator starts up reliably?
  To ensure reliable startup, Abracon recommends a power-up ramp time of 1ms to 10ms, and a power supply voltage of 1.8V to 3.3V. Additionally, the oscillator should be decoupled with a 0.01uF to 0.1uF capacitor between VCC and GND.
• What is the operating temperature range for this oscillator?
  The ARJ11B-MESBQ-A-B-EMU2 has an operating temperature range of -40°C to +85°C, making it suitable for industrial and commercial applications.
• Is the oscillator sensitive to EMI and RFI?
  Yes, the oscillator can be sensitive to EMI and RFI. Abracon recommends using EMI shielding, such as a metal can or a shielded enclosure, to minimize the effects of electromagnetic interference.
• Can I use this oscillator in a high-vibration environment?
  The ARJ11B-MESBQ-A-B-EMU2 is designed to withstand vibrations up to 20G, making it suitable for industrial and automotive applications. However, it's essential to ensure the oscillator is properly mounted and secured to the PCB to prevent damage.
