RECURSIVE SERIALIZERS AND DESERIALIZERS

Abstract:

A serializer includes a recursive tree of serializer unit cells. Each serializer unit cell includes a multiplexer and a plurality of flip-flops coupled to the multiplexer. Each serializer unit cell contains a state machine defining operation of the corresponding serializer unit cell. The recursive tree is organized with upper level serializer unit cells disposed more closely to a serializer output than are lower level serializer unit cells. The recursive tree is configured such that each serializer unit cell that is adjacent to and in an upper position relative to a corresponding lower level serializer unit cell directs the corresponding lower level serializer unit cell to output data, and the corresponding lower level serializer unit cell communicates to the corresponding serializer unit cell when the corresponding lower level serializer unit cell is done outputting data.
