Dynamic spread-spectrum-clocking control

A method for communication link synchronization, the method comprising:

• performing, at a first re-timer, a first clock signal recovery of a first clock signal subsequent to exiting a low-power communication link mode;
• generating, at a receiver, a spread-spectrum-clocking modulation enablement control signal responsive to the first clock signal recovery;
• and
• sending, responsive to receiving the spread-spectrum-clocking modulation enablement control signal, communication data from a transmitter with spread-spectrum-clocking modulation enabled through the first re-timer to the receiver.

At least one non-transitory machine-readable storage medium, comprising instructions that, responsive to being executed with processor circuitry of a computer-controlled device, cause the processor circuitry to:

• perform, at a first re-timer, a first clock signal recovery of a first clock signal subsequent to exiting a low-power communication link mode;
• generate, at a receiver, a spread-spectrum-clocking modulation enablement control signal responsive to the first clock signal recovery;
• and
• send, responsive to receiving the spread-spectrum-clocking modulation enablement control signal, communication data from a transmitter with spread-spectrum-clocking modulation enabled through the first re-timer to the receiver.
