Abstract
In the transmitting chip, the bits are serialized and applied to a coding circuit in which bit stream (D) and its complement (D) are transformed into two signals (PH1 and PH2) under the control of a saw-tooth clock signal CK'. Signals (PH1 and PH2) are sent to the receiving chip, wherein they are applied to a decoding circuit which generates two signals (DJ) and (DK) representative of the data bits and a recovered clock signal CLK. The three signals (DJ, DK and CLK) as well as a frame signal (F) are used by a converting and demultiplexing circuit for assembling bytes of parallel data bits.
