ABSTRACT:
A serializer within, for example, a transceiver is provided having multiple stages of pipelined multiplexing cells. Each multiplexing cell may be substantially the same and each comprises no more than one latch. In some embodiments, each multiplexing cell includes a multiplexer comprising a pair of inputs and a single latch, which is coupled to one input of the multiplexer. No latches are coupled to the other input of the multiplexer. The serializer generally includes a plurality of stages. Each successive stage includes one-half the number of multiplexing cells included in the previous stage, and each successive stage is clocked by a clocking signal that transitions at twice the frequency of the previous stage clock signal.
