CS47048C-DQZR Frequently Asked Questions (FAQs)

• What is the recommended power-up sequence for the CS47048C-DQZR?
  The recommended power-up sequence is to apply VDD first, followed by VDDA, and then the clock signal. This ensures proper initialization and prevents damage to the device.
• How do I optimize the performance of the CS47048C-DQZR in a noisy environment?
  To optimize performance in a noisy environment, use a low-pass filter on the analog input, ensure proper grounding and shielding, and consider using a ferrite bead or common-mode choke to reduce electromagnetic interference (EMI).
• What is the maximum clock frequency supported by the CS47048C-DQZR?
  The CS47048C-DQZR supports clock frequencies up to 192 kHz, but the maximum frequency may vary depending on the specific application and system requirements.
• How do I configure the CS47048C-DQZR for differential analog input?
  To configure the CS47048C-DQZR for differential analog input, connect the positive input signal to the IN+ pin and the negative input signal to the IN- pin, and ensure that the common-mode voltage is within the recommended range.
• What is the recommended layout and routing for the CS47048C-DQZR?
  For optimal performance, keep the analog and digital signal traces separate, use a solid ground plane, and minimize the length of the analog input traces. Also, ensure that the device is placed close to the analog signal source.
