Abstract
Within an integrated circuit a source of digital data is coupled to a distant destination by a serial data path that is characterized by being either an imperfect and lossy transmission line or as possessing significant high frequency attenuation. A single phase clock accompanies the data over the serial data path. A single phase to three phase clock generator at the destination creates the three phase clock. If the destination is a shift register, then the three phase clock can be used for stage-to-stage clocking within the shift register, as well as for getting data into the input bit of the shift register.
