CDCVF2310PW datasheet by Texas Instruments

CDCVF2310PW Frequently Asked Questions (FAQs)

• What is the recommended power-up sequence for the CDCVF2310PW?
  The recommended power-up sequence is to apply VCC before applying VDD. This ensures that the internal voltage regulators are powered up correctly.
• How do I ensure that the CDCVF2310PW is in a stable state during power-up?
  To ensure a stable state during power-up, it is recommended to add a power-on reset (POR) circuit to the VCC pin. This ensures that the device is reset properly during power-up.
• What is the maximum clock frequency that the CDCVF2310PW can support?
  The CDCVF2310PW can support clock frequencies up to 100 MHz. However, the actual frequency limit may be lower depending on the specific application and PCB layout.
• How do I optimize the PCB layout for the CDCVF2310PW?
  To optimize the PCB layout, it is recommended to follow the guidelines provided in the datasheet, including keeping the clock signal traces short and away from noise sources, and using a solid ground plane to reduce noise and EMI.
• What is the recommended termination scheme for the CDCVF2310PW?
  The recommended termination scheme is to use a series resistor (Rs) of 22-33 ohms and a parallel capacitor (Cp) of 10-22 pF at the output of the clock driver. This helps to reduce reflections and improve signal integrity.
