PCM1690DCA Frequently Asked Questions (FAQs)

  • The recommended power-up sequence is to apply VCC first, followed by VDD, and then the analog power supplies (VAA and VDA). This ensures that the internal voltage regulators are powered up correctly.
  • To minimize noise and ensure optimal performance, it is recommended to keep the analog and digital power supplies separate, use a solid ground plane, and keep the signal traces short and away from the power supply lines.
  • The maximum allowed clock jitter for the PCM1690DCA is 100 ps RMS. Exceeding this limit may result in decreased performance or errors in the audio data.
  • Yes, the PCM1690DCA can be used with a separate ADC. However, the ADC must be compatible with the PCM1690DCA's analog input requirements, and the system designer must ensure that the ADC's output is properly formatted for the PCM1690DCA's digital input.
  • To troubleshoot issues with the PCM1690DCA's digital output, check the clock signals, ensure that the correct format is selected, and verify that the digital output is properly terminated. Also, check the device's register settings and ensure that the correct mode is selected.
