DEVICE AND METHOD FOR TRANSMITTING DIGITAL DATA

摘要

A device for transmitting digital data which is provided with a converting block (4B/5B CONVERTER AND ARB. SIGNAL CONVERTER) (3) which functions not only as a 4-bit/5-bit converting means that performs 4-bit/5-bit conversion on data, but also as an arbitration signal converting means that assigns to arbitration signals 5-bit symbols other than those assigned to the data in the course of the 4-bit/5-bit conversion, whereby the device can transmit and receive arbitration signals and packet data as 5-bit code data. Since the device is also provided with scramble blocks (SCRAMBLE1 and SCRAMBLE2) (4A and 4B) and descramble blocks (DESCRAMBLE1 and DESCRAMBLE2) (5a and 5B) between the above converting block (3) and each of input and output ports, the device can prevent unnecessary radiation on a transmission line.
