LOW VOLTAGE DIFFERENTIAL SIGNALING(LSD) COMMUNICATION SYSTEM

摘要

PURPOSE: A low voltage differential signaling(LSD) communication system is provided to set up resistors on stub transmission lines connected with memory devices to control resistance, so as to prevent impedance mismatching caused when length of the stub transmission lines becomes longer. CONSTITUTION: Many integrated circuits(ICs) transceive low voltage differential signaling(LSD) signals. First/second main transmission lines(L1,L2) transmit the LSD signals. First stub transmission lines(S11-Sn1) connected between the ICs and the first main transmission line transmit the LSD signals. Second stub transmission lines(S12-Sn2) connected between the ICs and the second main transmission line transmit the LSD signals. Resisters(R1-Rn) correspond to the ICs, respectively, and are connected between the first stub transmission lines and the second stub transmission lines.
