Patent ID: 8842745

Claim:
A differential voltage driving type transmitter comprising: a voltage source configured to source a voltage to any one transmission line of a pair of transmission lines and sink a voltage from the other transmission line; a transmission direction selecting block configured to transfer voltage-type data from the voltage source to any one transmission line of the pair of transmission lines and transfer voltage-type data flowing through the other transmission line to the voltage source; and an equalizing switch block configured to initialize the pair of transmission lines into an equalized state, the voltage source comprising: a first voltage source having one terminal which is connected to a first voltage and the other terminal which is connected to a first terminal of the transmission direction selecting block; and a second voltage source having one terminal which is connected to a second voltage and the other terminal which is connected to a second terminal of the transmission direction selecting block; and the equalizing switch block comprising: an equalizing switch having one terminal which is connected to a first transmission line and the other terminal which is connected to a second transmission line; and a resistor component disposed between the first transmission line and the equalizing switch or between the equalizing switch and the second transmission line, wherein a value of the resistor component can be controlled.
