Method and apparatus for parallel in serial out transmission |
摘要 |
A method and apparatus for providing serial transmission of a parallel input is accomplished by a parallel input serial output transmitter that includes a shift register operably coupled to receive a parallel input and to provide data serially to a gating circuit. The gating circuit, based on the state of the data it receives, generates a drive signal which causes a switching circuit to route current from a first current source to a second current source over different paths to produce a serial output. A bias circuit is coupled to the switching circuit to bias the serial output to a desired level.
