CA25C2504GLT - CTS

CA25C2504GLT Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal performance of the CA25C2504GLT?
  CTS Corporation recommends a 4-layer PCB with a solid ground plane, and to keep the crystal oscillator traces as short and shielded as possible to minimize noise and radiation.
• How do I ensure the CA25C2504GLT oscillator starts up reliably in my design?
  CTS recommends using a 1-2 kΩ pull-up resistor on the oscillator output pin, and ensuring the power supply voltage is stable and within the recommended range before enabling the oscillator.
• What is the maximum allowable crystal load capacitance for the CA25C2504GLT?
  The maximum allowable crystal load capacitance is 20 pF, as specified in the datasheet. Exceeding this value may affect the oscillator's start-up time and frequency stability.
• Can I use a different crystal frequency with the CA25C2504GLT?
  Yes, but the CA25C2504GLT is optimized for 25 MHz operation. Using a different crystal frequency may require adjustments to the PCB layout, component values, and potentially affect the oscillator's performance and stability.
• How do I troubleshoot issues with the CA25C2504GLT oscillator not starting up or running at the correct frequency?
  CTS recommends checking the power supply voltage, crystal oscillator circuitry, and PCB layout for any defects or noise sources. Also, verify that the oscillator is properly enabled and configured according to the datasheet.
