ARJM11A1-502-JJ-EW2 - ABRACON

ARJM11A1-502-JJ-EW2 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 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.
• What is the operating temperature range for this oscillator?
  The ARJM11A1-502-JJ-EW2 has an operating temperature range of -40°C to +85°C. However, the frequency stability and aging characteristics may vary outside the recommended temperature range of 0°C to +70°C.
• Can I use this oscillator in a high-vibration environment?
  The ARJM11A1-502-JJ-EW2 is designed to withstand vibrations up to 20G. However, it's recommended to consult Abracon's application note AN-05 for vibration testing and mounting guidelines to ensure reliable operation.
• What is the equivalent series resistance (ESR) of the internal capacitors?
  The internal capacitors of the ARJM11A1-502-JJ-EW2 have an ESR of approximately 5 ohms. This value is not explicitly stated in the datasheet, but it's available in Abracon's application notes and technical support resources.
