CSTNE24M0VH3C000R0 - Murata Electronics

CSTNE24M0VH3C000R0 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 crystal's oscillation signal.
• How do I ensure the oscillator starts up reliably in my design?
  To ensure reliable startup, ensure the power supply voltage is stable and within the recommended range (1.8V to 3.6V). Add a 10nF to 100nF decoupling capacitor between VCC and GND near the oscillator. Also, avoid applying a clock signal to the output pin during startup.
• What is the maximum operating temperature range for this oscillator?
  The CSTNE24M0VH3C000R0 is rated for operation from -40°C to +85°C. However, the frequency tolerance and stability may degrade at extreme temperatures. For optimal performance, operate the oscillator within the recommended temperature range.
• Can I use this oscillator in a design that requires low EMI?
  Yes, the CSTNE24M0VH3C000R0 is designed to minimize EMI. However, to further reduce EMI, ensure the oscillator is placed away from the PCB edge, use a shielded enclosure, and add EMI filtering components (e.g., ferrite beads) on the power supply lines.
• How do I handle the oscillator's output signal in my design?
  The CSTNE24M0VH3C000R0 outputs a CMOS-level signal. Ensure the receiving circuitry is compatible with CMOS levels and can handle the output frequency (24MHz). Use a suitable signal termination (e.g., series resistor) to prevent signal reflections and ensure signal integrity.
