INCREASING THROUGHPUT ON MULTI-WIRE AND MULTI-LANE INTERFACES
Abstract:
Systems, methods and apparatus extract data and clocks from a multi-wire bus that includes a first lane operated in accordance with a camera control interface (CCIe) mode of operation or a first lane operated in accordance with an N! mode of operation. Timing information derived from a sequence of symbols received from the first lane may be used to deserialize data received on a second lane of the multi-wire bus or decode a sequence of symbols received on the second lane. The symbols in a pair of consecutive symbols transmitted on the first lane cause different signaling states. Data on the second lane may be deserialized using on the receive clock derived from the timing information. In a CCIe lane, the final symbol of the sequence of symbols may be suppressed or a setup condition curtailed when the final symbol produces a signaling state equivalent to the setup condition.
