CDCE72010RGCT Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for the CDCE72010RGCT to minimize noise and ensure optimal performance?
  A good PCB layout for the CDCE72010RGCT involves keeping the input and output traces short and separate, using a solid ground plane, and placing decoupling capacitors close to the device. TI provides a recommended layout in the datasheet and application notes.
• How do I choose the correct output frequency for my application?
  The output frequency of the CDCE72010RGCT depends on the input frequency, multiplication factor, and division factor. Use TI's Clock Design Tool or consult the datasheet to determine the correct output frequency for your specific application.
• What is the maximum input frequency that the CDCE72010RGCT can handle?
  The CDCE72010RGCT can handle input frequencies up to 250 MHz. However, the maximum input frequency may be limited by the specific application and PCB layout.
• How do I ensure that the CDCE72010RGCT is properly powered and decoupled?
  The CDCE72010RGCT requires a stable power supply and proper decoupling to ensure optimal performance. Use a low-ESR capacitor (e.g., 0.1 μF) close to the device and follow TI's recommended power supply filtering and decoupling guidelines.
• What is the typical jitter performance of the CDCE72010RGCT?
  The CDCE72010RGCT has a typical jitter performance of <1 ps RMS (12 kHz to 20 MHz) and <2 ps RMS (100 kHz to 20 MHz). However, actual jitter performance may vary depending on the specific application and PCB layout.
