Patent ID: 8797063

Claim:
A data transmission device comprising: a control unit configured to output a first control signal through an nth control signal, where n is a natural number; and a delay chain unit including a first switching element through an nth switching element that receive a first data signal through an nth data signal, respectively, and that perform pipelining operations on the first data signal through nth data signal based upon the first control signal through nth control signal, respectively, to output pipelined data signals as at least one data stream, the first switching element through nth switching element being connected to each other to form at least one data delay chain, wherein the control unit sequentially activates the control signals so that the data signals are sequentially outputted as the at least one data stream in response to the sequentially activated control signals, and wherein an interval between activation timings of two control signals corresponding to two adjacent switching elements is longer than a propagation delay of each switching element.
