CDCVF855PWR datasheet by Texas Instruments

CDCVF855PWR Frequently Asked Questions (FAQs)

• What is the recommended power-up sequence for the CDCVF855PWR?
  The recommended power-up sequence is to apply VCC first, followed by VCCO, and then the input clock signal. This ensures proper device operation and prevents potential latch-up conditions.
• How do I ensure proper termination for the output signals?
  The CDCVF855PWR requires a 50-ohm termination resistor to VCCO for each output signal. This ensures proper signal integrity and minimizes reflections.
• What is the maximum input clock frequency supported by the CDCVF855PWR?
  The CDCVF855PWR can support input clock frequencies up to 250 MHz. However, the maximum frequency may vary depending on the specific application and output frequency requirements.
• Can I use the CDCVF855PWR in a 3.3V system?
  Yes, the CDCVF855PWR can operate with a 3.3V supply voltage (VCCO). However, the input clock signal amplitude should be adjusted accordingly to ensure proper operation.
• How do I configure the CDCVF855PWR for a specific output frequency?
  The CDCVF855PWR has a programmable divider that allows for flexible output frequency configuration. The divider ratio can be set using the SEL0-SEL2 pins. Refer to the datasheet for specific configuration details.
