Abstract:
1. A system for serially transmitting data, the system comprising: a first communication terminal for outputting one or more parallel data signals and one or more clock signals corresponding to the parallel data signals; an external clock source for generating a reference clock signal; and a serializer for generating a serial clock signal on the basis of the reference clock signal and converting the parallel data signals received from the first communication terminal into one serial data signal, the serial clock being independent of the clock signals, wherein when a first parallel data signal and a second parallel data signal in synchronization with different clock frequencies are inputted into the serializer, the serializer generates the serial data signal having a bandwidth wider than a sum of the bandwidth of the first and second parallel data and transferring the first and second parallel data, wherein a frequency of the serial clock is adjusted so that the first and second parallel data signals are transmitted in the serial data signal, wherein the second parallel data signal is a data signal that has no synchronization signal and is to be transmitted within a predetermined duration, and wherein the serializer transmits a synchronization signal in a single packet and transmit the first parallel data signal between successive synchronization signals in the form of a single packet or several packets, and transmits the second parallel data signal between the successive synchronization signals in the form of a single packet or several packets subsequently to the packet of the first parallel data signal.
