Abstract
A deserializer within, for example, a transceiver is provided having multiple stages of pipelined demultiplexers. Each demultiplexer within the earlier stages of the pipelined architecture use only three latches. Two latches are dedicated to producing an odd bitstream (or even bitstream) from odd and even bits within the incoming serial bitstream. Another latch is dedicated to producing an even bitstream (or odd bitstream) from even and odd bits of the serial bitstream. Using only three latches within early stages of the pipelined architecture reduces power consumption and overall size of the deserializer. Clocking signal frequencies of subsequent stages are reduced and the clocking signals are delayed in order to align data outputs from the previous stage with transitions of clocking signals forwarded to the respective stages.
