Abstract: A receiver for clock reconstitution in a semiconductor field includes a termination resistor arranged between two input stages, to which a pair of input signals are input, the termination resistor including a first resistor and a second resistor; a strobe signal generator for generating a strobe signal, using a first signal corresponding to a differential voltage output from a node between the first resistor and the second resistor; and a clock reconstitutor for generating a clock signal in response to the strobe signal generated from the strobe signal generator.

Abstract: A transmitter for supplying a large current upon phase change of an output voltage is disclosed.

Abstract: A data transmitting system is provided that includes a transmitter that suppresses coupling noise by being operated using a differential voltage driving scheme at the time of transmitting data and being operated using a common voltage driving scheme by equalizing potential of a pair of transmission lines during a transition interval; and a receiver that is connected to the transmitter through the pair of transmission lines and recovers the data by sensing the voltage difference in signals of the pair of transmission lines.

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.
