Disclosed is a feed forward clock and data recovery unit for recovering a
received serial data bit stream having a feed forward phase tracking unit
for tracking of a sampling time to the center of a unit interval of the
received data bit stream. The feed forward phase tracking unit can
include a sampling phase generation unit, an oversampling unit, a
serial-to-parallel-conversion unit, a binary phase detection unit, a loop
filter, a finite state machine, a binary rotator, and a data recognition
unit for recovery of the received data stream which includes a number of
parallel data recognition FIR-Filters. Further, each data recognition
FIR-Filter can include a weighting unit for weighting data samples of the
deserialized data stream, a summing unit for summing up the weighted data
samples, and a comparator unit for comparing the summed up data samples
with a threshold value.
