    • A circuit for integrating serial-to-parallel conversion, parallel-to-serial conversion, and FIFO(First Input First Output) is provided to reduce a scale of the circuit, and improve consumption power and fast processing by integrating a serial-to-parallel conversion circuit, a parallel-to-serial conversion circuit, and a FIFO circuit. A register(1) samples data by receiving data in serial and outputs multiple sample data in parallel. A selector(2) receives the sample data from the register and selects one of the received sample data according to a received control signal. A control signal generation circuit generates the control signal inputted to the selector to make the data output from the selector in serial by matching with order for inputting the data to the register in serial. The register performs a serial-to-parallel conversion function for converting the data inputted in serial into the parallel data. The order for outputting the data from the selector in serial gets equal order for inputting the data to the register in serial.

    • A pre-emphasis circuit is provided to acquire timing relaxation, latency reduction, improvement of operational limitation, and reduction of a circuit by removing a high speed operation circuit without using a differential circuit. A first parallel-serial conversion circuit(1011) receives parallel data and converts the parallel data into first serial data. A mixing circuit(103) receives the first serial data outputted from the first parallel-serial conversion circuit(1011) and second serial data which is delayed as long as a predetermined time from the first serial data. The mixing circuit(103) generates a signal of a pre-emphasis amplitude in response to a shift of the first serial data. A second parallel-serial conversion circuit(1012) receives the parallel data with the first parallel-serial conversion circuit(1011). The second parallel-serial conversion circuit(1012) converts the parallel data into the second serial data. A delay circuit delays a conversion timing of the second parallel-serial conversion circuit(1012) as long as a predetermined delay time from a conversion timing of the first parallel-serial conversion circuit(1011).

    • A differential transmitter, a differential receiver, and a signal projector and a signal transmission system are provided to avoid the electrical energy consumption of the terminating resistor by turning off P-type transistor completely. A signal transmitter(110) outputs the differential output signals according to the input of differential input signals. Output terminals(105a,105b) output differential output signals from the transmitter signal transmitter. Transmission side terminating resistors(118a,118b) are parallely connected between the transmitter signal transmitter and output terminals. When the transmission side terminating resistor connection controller and differential input signals are inputted, the connection of transmission side terminating resistors is broken on the idle state where logic data are fixed from the transmitter signal transmitter. The transmitter signal transmitter comprises the differential pair which is cultivated by transistors in order to output the differential output signal. The transmission side terminating resistor is connected to the drain of transistors forming the differential pair.
