CDCF5801DBQR Frequently Asked Questions (FAQs)

• What is the recommended operating voltage range for CDCF5801DBQR?
  The recommended operating voltage range for CDCF5801DBQR is 2.7V to 3.6V, although it can operate from 2.3V to 5.5V with reduced performance.
• How do I ensure proper power sequencing when using CDCF5801DBQR?
  To ensure proper power sequencing, apply power to VCC before applying power to VDD, and ensure that VCC is stable before enabling the clock input.
• What is the maximum clock frequency supported by CDCF5801DBQR?
  The maximum clock frequency supported by CDCF5801DBQR is 100 MHz, although it can operate at higher frequencies with reduced performance and increased power consumption.
• How do I handle clock domain crossing (CDC) when using CDCF5801DBQR?
  To handle CDC, use a clock domain crossing circuit or a FIFO to synchronize data between clock domains, and ensure that the clock frequency ratio is within the recommended range.
• What is the purpose of the SYNC input pin on CDCF5801DBQR?
  The SYNC input pin is used to synchronize the output data with the clock input, ensuring that the output data is valid on the rising edge of the clock.
