    Abstract: An isochronous output data stream format in which a single n bit word is transmitted as m multiple synchronous data streams where the length of the word transmitted in each data stream is n/m, the output data stream containing multiple isochronous different data rate data streams and one or more asynchronous data stream or streams. One bit from each of the m multiple synchronous data streams are combined and transmitted as a single signal at one of 2 analog levels. Data which is it desired to have a lower error rate than other data is transmitted in the synchronous data stream corresponding to the most significant bit associated with the 2 analog levels. Calibration data is transmitted in the synchronous data stream corresponding to the most significant bit associated with the 2 analog levels, the calibration data also being transmitted distributed over each of the m synchronous data streams.
