    摘要: A serial data transmission system in which a transmitter encodes data in accordance with a TMDS-like encoding algorithm and transmits the TMDS-like encoded data over a serial link to a receiver. The encoded data are transmitted as a run length limited (“RLL”) code word sequence, including transition-minimized code words. In some embodiments, the RLL code word sequence includes only Min words, including both DC balancing Min words and DC unbalancing Min words. In other embodiments, the RLL code word sequence includes both transition-maximized code words and transition-minimized code words. Other aspects of the invention are circuitry and methods for TMDS-like encoding of data for transmission as an RLL code word sequence.

    摘要: A data sampling method and circuit employing an oversampling clock to oversample a data signal, a phase tracker for use with or in a data sampling circuit, and a method for identifying a sequence of best sampling positions for sampling a data signal from signal samples generated using an oversampling clock. In some embodiments, data indicative of the phase of at least one of the oversampling clock's sampling positions relative to the center of the data eye are low-pass filtered in a manner determined by the data signal's bit rate. In other embodiments, the number of dead cycles of the phase tracker decision loop is reduced by generating possible solutions in parallel and moving the feedback point so as to occur as late as practical, or the phase tracker ignores a sample set when updating its determination of the best sampling position when the sample set indicates that the data signal has less than a predetermined number of transitions during a corresponding tracking period.

    摘要: A data sampling circuit that employs an oversampling clock to oversample a data signal, a phase tracking circuit for use in such a sampling circuit, and a receiver and system including such a sampling circuit. Preferably, phase tracking is implemented by systematically identifying and rejecting at least one worst sampling position, and sampling the data signal at a non-rejected sampling position. Preferably, phase tracking is accomplished by counting through-transitions of edges of the sampled data signal through each oversampling position, and rejecting an oversampling position having a highest count of through-transitions. In some embodiments, different phase tracking methods (at least one of which includes the step of generating through-transition counts) are used for different types of input data. Other aspects of the invention are methods for determining an oversampling position for oversampling a data signal, and methods for oversampling a data signal including by generating through-transition counts.
