Patent ID: 7460565

Claim:
A data demultiplexer for demultiplexing data from a communication link, the data demultiplexer comprising: a higher frequency data demultiplexer which demultiplexes the data on the communication link to an intermediate frequency signal in response to a first timing signal; a timing signal generator to generate a second timing signal in response to the first timing signal, wherein the second timing signal exhibits one pulse for every N pulses of the first timing signal, N being an integer value; and a lower frequency data demultiplexer coupled to the higher frequency demultiplexer which demultiplexes the intermediate frequency signal to a demultipiexed data signal in response to the second timing signal; wherein a maximum timing error of the second timing signal tolerable by the lower frequency demultiplexer substantially exceeds a maximum timing error of the first timing signal tolerable by the higher frequency demultiplexer.
