    Hi, Kai,

    When the PCM2707C is operated in bus-powered mode, the required power supplies are generated on-chip and only a decoupling cap is required. Altough the voltage of the supplies you mention is the same, it is not recommended to connect them together, only a decoupling cap should be placed on each of those pins.
