Zero standby power for powerline communication devices |
摘要 |
An embodiment is an integrated System on Chip (SoC) including a communication interface configured to implement a communication protocol including functional blocks that are energized or de-energized individually so that a minimum power consumption is used to receive and detect a signal, and a receiver identification (ID) detection function configured to determine whether the signal is intended for the device in which the SoC resides. The SoC further includes a power management function configured to control which functions in the SoC and/or device in which the SoC resides are energized or de-energized depending on the results of the receiver ID detection function, and a power source capable of energizing a minimum number of the functional blocks required to receive and detect a signal, wherein the power source can be used in a low power state and switched over to a main power supply when the SoC is energized. |

1. An integrated System on Chip (SoC) comprising:
a communication interface configured to implement a communication protocol comprising of functional blocks that are energized or de-energized individually so that a minimum power consumption is used to receive and detect a signal; a receiver identification (ID) detection function configured to determine whether the signal is intended for a device in which the SoC resides; a power management function configured to control which functions in the SoC and/or device in which the SoC resides are energized or de-energized depending on the results of the receiver ID detection function; and a power source capable of energizing a minimum number of the functional blocks required to receive and detect a signal, wherein the power source can be used in a low power state and switched over to a main power supply when the SoC is energized. |
