CDBLA455KCAY16-B0 - Murata Electronics

CDBLA455KCAY16-B0 Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal performance?
  Murata 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 handle the oscillator's start-up time and stability?
  The CDBLA455KCAY16-B0 has a typical start-up time of 2-5 ms. To ensure stability, allow the oscillator to stabilize for at least 10 ms before using its output. You can also add a reset circuit or a power-on reset (POR) to ensure a clean start-up.
• What is the recommended drive level for the oscillator's output?
  The recommended drive level for the CDBLA455KCAY16-B0's output is 15 pF ±10%. Exceeding this value may affect the oscillator's frequency stability and amplitude. Use a buffer or a capacitive divider to adjust the output drive level if necessary.
• How do I ensure the oscillator's frequency accuracy and stability over temperature?
  To ensure frequency accuracy and stability, use a high-quality crystal with a low frequency tolerance (e.g., ±10 ppm). Also, consider using a temperature-compensated crystal oscillator (TCXO) or a voltage-controlled crystal oscillator (VCXO) if your application requires high frequency stability over a wide temperature range.
• What is the maximum operating temperature range for the oscillator?
  The CDBLA455KCAY16-B0 is rated for operation from -40°C to +85°C. However, the oscillator's frequency stability and accuracy may degrade at extreme temperatures. Consult the datasheet and Murata's application notes for more information on temperature-related performance.
