Basically given a sequence of two bits, the decorrelator will: + +0, 1: Emit 1 +1, 0: Emit 0 +0, 0: Emit nothing +1, 1: Emit nothing + +The rate of bits emitted is thus at most half of the bitrate on the +input. + +The module is synchronous, but bits may arrive a number of cycles +between eachother. The module will set the syn_out flag during one cycle +to signal that the value in data_out is a valid bit. + |
