Transition enforcing coding receiver for sampling vector signals without using clock and data recovery
A transition enforcing coding (TEC) receiver includes a delay line circuit, a transition detection circuit, a data sampling circuit, and a skew calibration circuit. The delay line circuit employs a calibrated delay setting to delay a plurality of vector signals to generate a plurality of delayed vector signals under a normal mode, respectively. The transition detection circuit detects a transition of at least one specific delayed vector signal among the delayed vector signals. The data sampling circuit samples the vector signals according to a sampling timing, wherein the sampling timing is determined based on an output of the transition detection circuit. The skew calibration circuit sets the calibrated delay setting under a calibration mode, wherein transition skew between different delayed vector signals is reduced by the calibrated delay setting under the normal mode.
