ABSTRACT:
A data interfacing system for asynchronous data which has a predetermined data format and receives a data group transmitted in an asynchronous manner, uses a predetermined basic clock signal in providing synchronism to asynchronous data group. The system generates a line recognizing signal corresponding to each data line in the particular format of the data group, generates a line clock signal having a predetermined pulse at the end point of each data line in response to the line recognizing signal and the basic clock signal. The system also generates a pulse signal having a period corresponding to a single data bit of the data group by counting the basic clock signal during a data bit section enabled by the line recognizing signal. The data is fed to a shift register permitting particular data to be extracted synchronously from the data group. A corresponding data interfacing method is also described.
