Clock recovery method for bursty communications. A method is disclosed for
recovering the clock from a received data stream that comprising bursts of data
with zones of substantially no data between the bursts of data. A receive clock
is provided that operates within a reference frequency range. The time between
data transitions in the received data is then measuring relative to the receive
clock. A determination is then made if the measured time is substantially an integral
of the receive clock. If not a substantial integral of the receive clock, the frequency
of the receive clock is adjusted to compensate for the difference.
