Differential signal transmission circuit

A differential signal transmission circuit for transmitting a high speed signal through a differential transmission line, comprising:

• a plurality of transmission channels for transmitting high speed pulse signals generated by an LSI circuit, each of the transmission channel is comprised of:
• a CMOS (Complementary Metal Oxide Semiconductor) differential driver for receiving a high speed signal to be transmitted from the LSI circuit and providing the high speed signal to a differential transmission cable;
• an impedance matching circuit connected between an output of the CMOS differential driver and ground to substantially decrease an output impedance of the CMOS differential driver;
• a series termination circuit provided between the output of the CMOS differential driver and the differential transmission cable to match a sum of resistance of the series transmission circuit and an overall impedance at the output of the driver with a characteristic impedance of the differential transmission cable;
• and
• a differential receiver provided at an end of the differential transmission cable for receiving and reproducing the high speed signal through the differential transmission cable;
• wherein the CMOS differential driver in each transmission channel is integrated into the LSI circuit, and wherein the LSI circuit is a CMOS integrated circuit.
