CS42516-CQZR datasheet by Cirrus Logic

CS42516-CQZR Frequently Asked Questions (FAQs)

• What is the recommended power-up sequence for the CS42516-CQZR?
  The recommended power-up sequence is to apply VCC first, followed by VDD, and then the clock signal. This ensures proper initialization and prevents damage to the device.
• How do I optimize the performance of the CS42516-CQZR 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 on the power supply lines.
• What is the maximum clock frequency supported by the CS42516-CQZR?
  The maximum clock frequency supported by the CS42516-CQZR is 192 kHz. However, it's recommended to use a clock frequency of 176.4 kHz or 192 kHz for optimal performance.
• Can I use the CS42516-CQZR in a differential mode?
  Yes, the CS42516-CQZR can be used in a differential mode by connecting the analog input signals to the IN+ and IN- pins. This can help to reduce common-mode noise and improve overall performance.
• How do I handle the digital output data from the CS42516-CQZR?
  The digital output data from the CS42516-CQZR is in a 24-bit, 2's complement format. You can handle this data by using a microcontroller or DSP to process the output, or by using a dedicated audio codec or processor.
