Method and apparatus for converting interface between high speed data having various capacities

A digital communicating apparatus comprising:

• a first communicating device for accommodating data having a second data capacity and a third data capacity as well as a first data capacity using a plurality of channels through which data having the first data capacity is transmitted and received;
• and
• an interface converting apparatus for generating a deskew channel when a plurality of data is transmitted from the first communicating device, outputting the deskew channel together with the plurality of data to a second communicating device, removing skew of the plurality of data using the deskew channel when the deskew channel and the data are transmitted from the second communicating device, and transmitting the data to the first communicating device.

A method for converting an interface, the method comprising:

• generating a deskew channel having respective timing data of a plurality of data transmitted from a first communicating device, and outputting the generated deskew channel together with the data to a second communicating device;
• and
• comparing the deskew channel transmitted from the second communicating device with the plurality of data to measure skew values of the plurality of data, aligning bits and bytes of the data using the skew values, and transmitting the data to the first communicating device.
