CDC351DBR Frequently Asked Questions (FAQs)

  • 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.
  • When using the CDC351DBR in a system with multiple clock domains, it's essential to ensure that the clock signal is properly synchronized and buffered to prevent clock domain crossing issues. Use a clock buffer or a clock domain crossing circuit to synchronize the clock signal.
  • The maximum frequency of operation for the CDC351DBR 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 CDC351DBR does not have a dedicated reset pin. Instead, you can use the asynchronous reset signal (ASYNC_RST) or the synchronous reset signal (SYNC_RST) to reset the device. The choice of reset signal depends on the system's requirements and clock domain architecture.
  • The recommended termination scheme for the CDC351DBR's output signals is to use a series resistor (Rs) and a parallel capacitor (Cp) to match the transmission line impedance. The values of Rs and Cp depend on the system's specific requirements and PCB layout.
