CDC328ADBR datasheet by Texas Instruments

CDC328ADBR Frequently Asked Questions (FAQs)

• What is the recommended power-up sequence for the CDC328ADBR?
  The recommended power-up sequence is to apply VCC before applying VREF. This ensures that the internal voltage regulator is powered up correctly.
• How do I ensure that the CDC328ADBR is in a stable state during power-up?
  To ensure a stable state during power-up, it is recommended to add a power-on reset (POR) circuit to the VCC pin. This ensures that the device is reset properly during power-up.
• What is the maximum clock frequency that the CDC328ADBR can support?
  The CDC328ADBR can support clock frequencies up to 100 MHz. However, the actual clock frequency supported may be limited by the specific application and PCB design.
• How do I optimize the CDC328ADBR for low power consumption?
  To optimize the CDC328ADBR for low power consumption, it is recommended to use the lowest possible clock frequency, disable unused features, and use the power-down mode when the device is not in use.
• What is the recommended layout and routing for the CDC328ADBR?
  The recommended layout and routing for the CDC328ADBR involves keeping the analog and digital signals separate, using a solid ground plane, and minimizing the length of the clock signal traces.
