CDCEL949PW Frequently Asked Questions (FAQs)

  • Texas Instruments recommends a 4-layer PCB with a solid ground plane, and to keep the input and output traces as short as possible. Additionally, use a common mode choke or ferrite bead to filter the input power and reduce EMI.
  • The CDCEL949PW requires a single 3.3V or 5V power supply. Ensure the power supply is stable and has a low noise floor. Power sequencing is not critical, but it's recommended to power the device after the input clock is stable.
  • The CDCEL949PW can handle clock frequencies up to 200 MHz. However, the maximum frequency may vary depending on the specific application and output load.
  • The CDCEL949PW can be configured using the SEL0-SEL2 pins to select one of 16 possible output frequencies. The output frequency range is from 25 MHz to 200 MHz. The device can also be used in a voltage-controlled oscillator (VCO) mode to generate frequencies outside of the predefined range.
  • The CDCEL949PW has a typical jitter performance of 150 fs RMS. Jitter can affect the system by causing errors in data transmission, increasing bit error rates, and reducing the overall system reliability.
