226AMVAAR - CTS

226AMVAAR Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal performance of the 226AMVAAR?
  CTS Corporation recommends a 4-layer PCB with a solid ground plane, and a separate power plane for the oscillator circuit. Additionally, keep the oscillator circuit away from noisy digital signals and ensure a low-impedance path for the oscillator output.
• How do I ensure the 226AMVAAR oscillator starts up reliably in my application?
  To ensure reliable startup, ensure the power supply voltage is stable and within the recommended range, and that the oscillator circuit is properly decoupled with a 10nF to 100nF capacitor. Also, avoid applying a clock signal to the oscillator input during startup.
• What is the maximum allowable frequency deviation for the 226AMVAAR?
  The maximum allowable frequency deviation is ±50 ppm over the entire operating temperature range of -40°C to +85°C. This deviation is due to the internal oscillator's natural frequency variation and can be affected by factors such as temperature, voltage, and aging.
• Can I use the 226AMVAAR in a system with a different clock frequency?
  Yes, the 226AMVAAR can be used in systems with different clock frequencies. However, the internal oscillator frequency must be divided or multiplied using an external clock divider or multiplier circuit to match the system clock frequency.
• How do I troubleshoot issues with the 226AMVAAR oscillator not oscillating?
  To troubleshoot oscillator issues, check the power supply voltage, ensure the oscillator circuit is properly decoupled, and verify that the oscillator input is not being driven by an external clock signal. Also, check for any signs of damage or contamination on the device or PCB.
