CHANNEL TIME CALIBRATION MEANS

摘要

A data transmission means and method employing the phase noise characteristics within the receiving registers to measure and control the characteristics of the channel as a function of the data pattern and to compensate for production tolerances within the channel by altering the timing characteristics of the signal at either the transmitter or receiver as a function of the data. The data transmission means for high-speed transmission of digital data according to the invention comprises - a communicational channel between a transmitter and a receiver, - a main clock and a reference clock, - a means for measuring time offsets between different signals that form the communication channel, at different frequencies, and/or for different data patterns transmitted through the channel; - a storage means for storing the measured time offsets; and - a timing correction means for applying the measured time offsets to compensate for said inter-signal skew by performing relative alignment of the measured offsets to the main clock edge.
