I need to reduce the power on DM8148 during standby mode. What are the different power down mode available in the device and what is minimum power required for the devicve in sleep or low power mode. I also need to provide wake on lan feature on the same device. I think I can provide this feature by using a PHY device which support wake on lan feature. Is there any time constraint for the device to come out of sleep mode when wake on lan packet arrives.
