9B-22.1184MAAJ-B - TXC CORPORATION

9B-22.1184MAAJ-B Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal performance?
  TXC recommends a symmetrical PCB layout with a ground plane underneath the oscillator to minimize noise and radiation. A 4-layer PCB with a dedicated ground layer is ideal. Keep the oscillator away from high-frequency components and ensure a clear return path for the ground connection.
• How do I ensure the oscillator starts up reliably?
  To ensure reliable startup, TXC recommends a power-up ramp time of at least 1 ms/V. A slower power-up ramp can help prevent the oscillator from malfunctioning or not starting up at all. Additionally, ensure the power supply is stable and within the recommended operating range.
• What is the maximum allowable frequency deviation due to temperature changes?
  The 9B-22.1184MAAJ-B has a specified frequency tolerance of ±20 ppm over the operating temperature range of -40°C to +85°C. This means the frequency can deviate by up to ±3.776 kHz (20 ppm of 11840000 Hz) due to temperature changes.
• Can I use this oscillator in a high-vibration environment?
  While the 9B-22.1184MAAJ-B is designed to be robust, it's still a sensitive component. TXC recommends limiting vibration to 10 G peak acceleration in the frequency range of 10 Hz to 2 kHz. Excessive vibration can cause frequency instability or even damage the oscillator.
• What is the recommended storage condition to prevent damage or degradation?
  Store the 9B-22.1184MAAJ-B in a dry, cool place with a temperature range of -40°C to +30°C and relative humidity below 80%. Avoid exposing the oscillator to direct sunlight, moisture, or extreme temperatures during storage.
