Abstract
Systems and methods are provided for managing power of a device coupled with a transceiver module, in communication with a high-speed interface. In one aspect, a dynamic clock trunk tree associated with the transceiver module is controlled by a trunk driver having a first clock tree gate. A dynamic clock leaf tree associated with the device is controlled by a leaf driver having a second clock tree gate. Significant power savings may be achieved, for example, by triggering activation of clock gating mechanisms.
