PCM1801U Frequently Asked Questions (FAQs)

  • The recommended power-on sequence is to apply VCC first, followed by VREF, and then the clock signal. This ensures proper initialization of the device.
  • To optimize the analog input stage, use a low-pass filter to remove high-frequency noise, and ensure the input signal is within the recommended common-mode voltage range (VCM). Also, use a high-impedance source and a low-capacitance layout to minimize signal attenuation.
  • The maximum allowed clock jitter is 100 ps RMS. Exceeding this value can result in decreased SNR and THD performance.
  • Yes, the PCM1801U can be used in a multi-channel audio application. However, each channel requires a separate PCM1801U device, and the master clock must be synchronized across all channels.
  • To ensure data integrity, use a reliable clock source, ensure proper synchronization between the ADC and the digital interface, and implement error detection and correction mechanisms in the digital interface.
