Abstract: A source driver and a liquid crystal display (LCD) device having the same. A source driver may carry a clock in a data current, and may recover a clock signal and/or a data signal without being substantially affected by external frequencies and/or resistance. A source driver may include a trans-impedance amplifier which may receive data currents, convert data currents into voltages, and/or output voltages as data voltages and/or clock voltages. A source driver may include a comparator electrically coupled to a trans-impedance amplifier, which may change levels of data and/or clock voltages applied from a trans-impedance amplifier, and/or may output level-changed voltages as data signals and/or a clock signal.

Abstract: A data transmitting device and a data receiving device are disclosed. The data transmitting device may include a clock signal generator for generating a clock signal, and a transmitter for generating a transmission signal having the clock signal inserted in a data signal, wherein the clock signal has only a single differential element, and the data signal has two differential elements with an amplitude identical to an amplitude of the clock signal. The clock signal may be embedded and the clock signal may be restored by using the common element of the data signal without any auxiliary reference voltage. As a result, only the data signal line may be used between the data transmitting device and the data receiving device, to reduce the number of transmitting lines. Furthermore, the data transmitting and receiving devices according to embodiments will not need a reference voltage. As a result, the clock signal may be restored smoothly even if the size of the data signal is changing.
