Systems and methods to provide a low-power mode for serial links are disclosed. One embodiment of such a system includes a transmitter coupled to a link; a receiver coupled to the link and configured to receive signals over the link from the transmitter; a transmit control module configured to cause the transmitter to enter and exit a low-power mode; and a clock module coupled to the transmitter and configured to provide a clock signal to the transmitter, wherein the clock module is further configured to provide the clock signal as a divided clock signal to the transmitter when the transmitter is in the low-power mode, further wherein the divided clock signal has a same phase as the clock signal before entry into the low-power mode.
