7R-24.000MEEC-T - TXC CORPORATION

7R-24.000MEEC-T 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 in my design?
  To ensure reliable startup, ensure the power supply voltage is stable and within the recommended range (1.8V to 3.3V). Add a 10nF to 100nF decoupling capacitor between VCC and GND near the oscillator. Also, avoid applying a clock signal to the oscillator input during startup.
• What is the maximum allowable frequency deviation due to temperature changes?
  The 7R-24.000MEEC-T has a frequency stability of ±20 ppm over the operating temperature range of -40°C to 85°C. This means the frequency deviation due to temperature changes is limited to ±480 Hz (20 ppm of 24 MHz).
• Can I use this oscillator in a design that requires a specific EMI reduction?
  The 7R-24.000MEEC-T has a built-in EMI reduction feature, which helps minimize electromagnetic interference. However, if your design requires additional EMI reduction, consider adding external components, such as a ferrite bead or a common-mode choke, to the oscillator output.
• What is the recommended storage condition to prevent damage or degradation?
  Store the 7R-24.000MEEC-T in a dry, cool place (temperature range: -40°C to 85°C) with relative humidity below 80%. Avoid exposing the device to direct sunlight, moisture, or extreme temperatures during storage.
