PCM5101A: PCM5100A application question

Part Number: PCM5101A

Hi teams

We have several questions about PCM510XA that need your help to figure it out.

  1. Compare to a device with 1Vrms maximum output voltage (SNR is 106dB). PCM5101A （2.1Vrms maximum output with 106dB). If we need to compare the parameters with a device with 1Vrms the actual SNR of PCM5101A should be 106dB-6dB? Am my calculation is right?
  2. If the reset pin of PCM5101A is low. Not matter the I2S come first than AVDD/PVDD or not won't influence the DAC?
