PCM4204: Power requirements

Part Number: PCM4204

Hi team,

Let me ask questions about power requirements.

1. Is there any requirements of power-on/power-off sequence of Vcc and Vdd? If I understand correctly, RESET OPERATION section describes initialization sequence, but this doesn't require specific sequence for power supply.

2. Is there any requirements of rise time/fall time of Vcc and Vdd?

Best regards,


  • Hi Hideki-san,

    There are not any strict power on/off timing requirements for PCM4204. I would just recommend holding the device in reset until the power rails have settled and all clocks are supplied so that the device initializes properly.
