CDCU877RHAR Frequently Asked Questions (FAQs)

  • The recommended power-up sequence is to apply VCC first, followed by VCCP, and then the clock signal. This ensures proper initialization and prevents damage to the device.
  • When using the CDCU877RHAR 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 CDCU877RHAR can handle clock frequencies up to 100 MHz. However, the actual frequency limit may vary depending on the specific application, PCB layout, and signal integrity.
  • The CDCU877RHAR can be configured to work with various PLLs or clock generators by adjusting the clock input pin (CLKIN) and the clock output pin (CLKOUT). Refer to the PLL or clock generator datasheet for specific configuration requirements.
  • The recommended termination scheme for the CDCU877RHAR's output signals is to use a series termination resistor (Rs) of 22-33 ohms, followed by a parallel termination capacitor (Cp) of 1-2 pF. This helps to reduce signal reflections and improve signal integrity.
