In a multi-channel device for the processing of digital data bytes comprised of parallel arrangements of data bits, the invention calls for recognition of the fact that-irrespective of skew and other interchannel variations in the processing of such data bits-the median-occurring bit of each successive data byte constitutes a good representative of the time of occurrence of the byte in question. By suitably buffering the bits of successive data bytes, a "median clock" that is slaved to the aforenoted "median-occurring" bits may be used to clock data bytes-devoid of inter-channel timing errors-out of the apparatus used for the indicated buffering operation.
