Abstract:
1. An apparatus for demultiplexing sampled data at a first data rate on a data line using a non-standard demultiplex mode comprising: means for demultiplexing the sampled data on the data line using a standard, factor of two, demultiplex mode to produce n data lines of sampled data at 1/n times the first data rate; and means for converting the n lines of sampled data to m data lines of sampled data at 1/m times the first data rate to produce the non-standard demultiplex mode, m being an integer less than n; wherein the converting means comprises: means for clocking the sampled data from the n data lines through a first set of n registers at a system clock rate to produce n first output lines; means for clocking the sampled data from n−1 of the n first output lines through a second set of n−1 registers at the system clock rate to produce n−1 second output lines; and means for multiplexing the sampled data from the first and second output lines to produce the m data lines of sampled data.
