Hi,

Can I leave VCCOB and VCCOC floating to save power when CLKOUTB and REFOUT are not used on the board?

Regards,

Wei

    Hi Wei,

    It is not recommended to leave VCCOB and VCCOC floating to save power. When CLKOUTB and REFOUT are not used on the board, the recommended way to save power is to leave each of the associated outputs floating, or disable them if possible. It is not possible to enable Bank A and disable Bank B, so the best route of action is to leave the outputs from Bank B floating, and to disable REFOUT.

    Thanks,

    Michael
