LOW-POWER, HIGH-SPEED TRANSMISSION AND RECEPTION DEVICE CAPABLE OF REDUCING THE POWER CONSUMPTION OF A TRANSMISSION DEVICE THROUGH THE INCREASE OF TERMINATING RESISTANCE OF THE TRANSMISSION AND RECEPTION DEVICE

摘要

PURPOSE: A low-power, high-speed transmission and reception device is provided to reduce power consumption of a transmitting-end circuit by making the terminating resistance value prepared at the transmitting-end circuit and a receiving-end circuit bigger than the characteristic impedance value of a transmission line, and to compensate for the electromagnetic wave reflection and the ISI(Inter-Symbol Interference) generated at the end of the transmitting-end circuit and receiving-end circuit due to the increase of the terminating resistance value.;CONSTITUTION: A receiving-end circuit(200) receiving signals from a transmitting-end circuit includes the following parts: a de-skew part(210) performing de-skew operations to remove skew between the data received from the transmitting-end circuit(100) and a clock; a DFE(Decision Feedback Equalization) circuit(220) compensating for the electromagnetic wave reflection and the ISI increase according to the control of a control part(250); a serial/parallel conversion part(230) converting output signals from the DFE circuit to serial/parallel signals and outputs the converted signals; a counter(240) feeding a part of output signals from the serial/parallel conversion part back to the control part; and a control part controlling general operations of the receiving-end circuit.;COPYRIGHT KIPO 2013;[Reference numerals] (210) De-skew part; (220) DFE circuit; (221) Initial stage circuit; (230) Serial/parallel conversion part; (240) Counter; (250) Control part
