Patent ID: 7064690

Claim:
A serializer for sending a data word out bit by bit, the serializer comprising: a register for holding the data word, the register having at least one data output and a control input; an output data port for serially outputting the data word bit by bit; means for connecting the data output to the output data port; a pulse generator free of external timing reference; means for connecting the pulse generator to the control input after a data word has been loaded into the register, wherein the data word bits are serially output in response to to the pulse generator; and means for adding at least two boundary bits to the serially output data word bits, wherein the added two bits always include a logic one and a logic zero in any order, and further wherein the means for connecting the pulse generator to the control input includes means for holding the signal at the control input at a constant logic level during the outputting of the at least two added bits.
