CDC341DW Frequently Asked Questions (FAQs)

• What is the recommended power-up sequence for the CDC341DW?
  The recommended power-up sequence is to apply VCC first, followed by VDD, and then the clock signal. This ensures proper initialization and prevents latch-up.
• How do I handle metastability issues in the CDC341DW?
  To minimize metastability issues, ensure that the input clock frequency is within the recommended range, and use a clock signal with a fast rise time. Additionally, consider using a clock domain crossing (CDC) circuit or a synchronizer to resynchronize the clock signal.
• What is the maximum clock frequency supported by the CDC341DW?
  The CDC341DW supports clock frequencies up to 100 MHz. However, the actual frequency limit may depend on the specific application, board layout, and signal integrity.
• Can I use the CDC341DW as a clock buffer or repeater?
  Yes, the CDC341DW can be used as a clock buffer or repeater. It can fan out a single clock input to multiple outputs, and its low-skew and low-jitter characteristics make it suitable for clock distribution applications.
• How do I ensure signal integrity when using the CDC341DW?
  To ensure signal integrity, use a low-impedance output termination, keep the clock signal traces short and well-shielded, and avoid using long clock signal traces or those with high capacitance. Additionally, consider using a clock signal with a 50-ohm impedance.
