CDC351DW Frequently Asked Questions (FAQs)

  • The recommended power-on sequence is to apply VCC first, followed by VDD, and then the clock signal. This ensures proper initialization and prevents latch-up.
  • When using the CDC351DW in a system with multiple clock domains, it's essential to ensure that the clock signal is properly synchronized and buffered to prevent metastability issues. Use a clock buffer or a clock domain crossing (CDC) circuit to synchronize the clock signal.
  • The maximum frequency of operation for the CDC351DW is 100 MHz. However, the actual frequency of operation may be limited by the system's clock signal quality, PCB layout, and other factors.
  • The CDC351DW does not have a dedicated reset pin. Instead, use the asynchronous reset input (RST) to reset the device. The RST pin should be asserted low for at least 2 clock cycles to ensure a proper reset.
  • The recommended termination scheme for the CDC351DW's outputs is to use a series resistor (Rs) of 22-33 ohms and a parallel capacitor (Cp) of 1-2 pF to the output pin. This helps to reduce signal reflections and improve signal integrity.
