APPARATUS AND METHOD FOR HIGE SPEED INTERFACING IN INTERGARATED CIRCUIT

A device and a method for interfacing ICs at high speed are provided to synchronize channels for data output of a serial gigabit receiver embedded in each IC, insert a comma when the embedded serial gigabit receiver inputs the continuous data, and prevent the embedded serial gigabit receiver from outputting a garbage value. A blank generator(303) generates a blank clock by adjusting a transfer rate of the data. A comma inserter(305) inserts the comma into the blank clock. A transmitter(309) transmits a bit string comprising the data and the comma to another IC. The generator includes a register sequentially storing the data received through 'N' buses, an extractor extracting the data stored in the register through 'N+1' buses, and a counter determining a data output time point. The generator stores the data received through the 'N+1' buses for a part of a time section, and stores and outputs the data received through the 'N+1' buses for the remaining time section at the same time.
