CDC328ADG4 datasheet by Texas Instruments

CDC328ADG4 Frequently Asked Questions (FAQs)

• What is the recommended power-up sequence for the CDC328ADG4?
  The recommended power-up sequence is to apply VCC first, followed by VREF, and then the clock signal. This ensures proper initialization of the device.
• How do I handle metastability in the CDC328ADG4?
  Metastability can be handled by using synchronizers, such as two-stage synchronizers, to resynchronize the data signals. Additionally, using a clock domain crossing (CDC) circuit can help to mitigate metastability issues.
• What is the maximum frequency of operation for the CDC328ADG4?
  The maximum frequency of operation for the CDC328ADG4 is 200 MHz. However, this frequency may vary depending on the specific application and system design.
• How do I implement clock domain crossing (CDC) with the CDC328ADG4?
  Clock domain crossing can be implemented using the CDC328ADG4 by using a CDC circuit that synchronizes the data signals between the two clock domains. This can be done using a combination of flip-flops and logic gates.
• What is the latency of the CDC328ADG4?
  The latency of the CDC328ADG4 is typically around 2-3 clock cycles, depending on the specific configuration and application.
