A method and system for transitioning a communication circuit to a low-power state are disclosed. Where a first device and a second device communicate over a communication link, the first device may initiate a transition from an active state to a low-power state to conserve energy. A symbol may be encoded by the first device in data and transmitted to the second device. The first device may deactivate one or more components when entering the low-power state. Additionally, responsive to receiving and decoding the symbol, the second device may deactivate one or more components when entering the low-power state. In this manner, energy consumption of one or more components can be reduced and a low-power state may be entered to conserve energy.
