  • Patent number: 11522738
    Abstract: High-speed communication links with self-aligned scrambling on a communication link that sends scrambled signals may include a slave device that may self-align by initially detecting an unscrambled preamble symbol and more particularly detect an edge of the unscrambled preamble symbol. Based on the detected edge, a fine alignment adjustment may be made by testing subsequent scrambled data for a repeated pattern such as an IDLE symbol by comparing the repeated pattern to a candidate scrambled sequence that has been received through the communication link. The comparison may use an exclusive OR (XOR) circuit on some bits to derive a scrambler seed that is used to test for a match for the remaining bits. If there is a match, the scrambler seed and frame alignment have been detected and alignment is achieved.

    Abstract: Disclosed herein are systems, methods, and devices for sensor systems, in which one or more sensors are linked with a host processor. The sensors may transmit a sequence of frames, such as video frames to the host processor. The methods may include determining and/or adjusting a period or frequency of a first clock or oscillator in a sensor device, based on two signals applied by the sensor to a sequence of frames. The host processor may use its own clock or oscillator to determine an elapsed time between the two signals to determine the period or frequency of the first clock and may apply an adjustment to the sensor's clock. Other embodiments are directed to sensor systems in which two or more sensors may transmit respective sequences of frames to the host processor. The methods may provide the host processor a means to synchronize transmission of the frames from the sensors. The systems, methods, and devices may avoid the need for dedicated timing or synchronization lines.
