CS4272K-CZZ - Cirrus Logic

CS4272K-CZZ Frequently Asked Questions (FAQs)

• What is the recommended power-up sequence for the CS4272K-CZZ?
  The recommended power-up sequence is to apply VDD first, followed by VCC, and then the clock signal. This ensures proper initialization of the device.
• How do I optimize the performance of the CS4272K-CZZ in a noisy environment?
  To optimize performance in a noisy environment, use a low-pass filter on the analog input, ensure good power supply decoupling, and use a shielded cable for the analog input. Additionally, consider using a common-mode filter on the analog input lines.
• What is the maximum allowed clock jitter for the CS4272K-CZZ?
  The maximum allowed clock jitter for the CS4272K-CZZ is 100 ps RMS. Exceeding this limit may result in decreased performance and increased distortion.
• Can I use the CS4272K-CZZ with a separate analog and digital power supply?
  Yes, the CS4272K-CZZ can be used with separate analog and digital power supplies. However, ensure that the analog power supply is well-regulated and has a low noise floor to maintain optimal performance.
• How do I troubleshoot issues with the CS4272K-CZZ's digital output?
  To troubleshoot issues with the digital output, check the clock signal, ensure proper synchronization, and verify that the digital output is properly terminated. Also, check the device's register settings and ensure that the correct format is selected.
