2.7.2.1.3. Power State Management
Power States | Description |
---|---|
P0 | Normal operating state during which packet data is transferred on the PCIe link. |
P0s, P1, and P2 | The PHY-MAC layer directs the physical layer to transition into these low-power states. |
The PIPE interface in Cyclone® 10 GX transceivers provides a pipe_powerdown[1:0] input port for each transceiver channel configured in a PIPE configuration.
The PCIe specification requires the physical layer device to implement power-saving measures when the P0 power state transitions to the low power states. Cyclone® 10 GX transceivers do not implement these power-saving measures except for putting the transmitter buffer in electrical idle mode in the lower power states.
