DP83849I: Clock module is enabled in POWER DOWN mode?

Hisao Uchikoshi

Part Number: DP83849I

Hi Experts,

In POWER DOWN mode, the PHY is power-down while the register is enabled. Is Clock module enabled even in POWER DOWN mode? The ICC for POWER DOWN mode is 9.5mA and not so small, I guess clock module or any other logic are enabled.

Hi Uchikoshi-san,

In power-down mode, the register access to the PHY is still available so some portion of the PHY is active. Its difficult to comment on exactly which blocks are active but this can be the reason for the current consumption.
