Abstract
A receiver circuit includes a feedback loop including a device. The receiver circuit also includes a register and a sequencer. The sequencer is configured to, responsive to an error signal being below a threshold value, cause the register to store a value indicative of the state of the feedback loop. The sequencer is also configured to cause the feedback loop to transition to a lower power state, and, responsive to a detected wake-up event, cause the previously stored value indicative of the state of the feedback loop to be loaded from the register into the device and enable the feedback loop.
Claims22
A method, comprising:
- responsive to an error signal being below a threshold value, storing a state value of a feedback loop;
- transitioning a device within the feedback loop to a lower power state;
- detecting a wake-up event;
- responsive to the detected wake-up event, loading a previously stored feedback loop state value;
- and
- enabling the feedback loop.
A receiver circuit, comprising:
- a feedback loop;
- a device comprising a register wherein the device is included in the feedback loop;
- and
- a sequencer coupled to the feedback loop, the sequencer configured to:
- responsive to an error signal being below a threshold value, cause the register to store a value indicative of the state of the feedback loop;
- cause the feedback loop to transition to a lower power state;
- responsive to a detected wake-up event, cause the previously stored value indicative of the state of the feedback loop to be loaded from the register into the device;
- and
- enable the feedback loop.
A receiver circuit, comprising:
- a feedback loop;
- a device comprising a register wherein the device is included in the feedback loop;
- and
- a sequencer coupled to the feedback loop, the sequencer configured to:
- adjust a threshold value based on a value indicative of a cable length;
- responsive to an error signal being below the threshold value, cause the register to store a value indicative of the state of the feedback loop;
- cause the feedback loop to transition to a lower power state;
- responsive to a detected wake-up event, cause the previously stored value indicative of the state of the feedback loop to be loaded from the register into the device;
- and
- enable the feedback loop.
