Error detection and compensation for a multiplexing transmitter

A method comprising:

• choosing a calibration mode selected from a plurality of different types of calibration modes, wherein the chosen calibration mode comprises a first error measurement associated with a first type of clock in a plurality of clocks, and another one of the plurality of different types of calibration modes comprises a second error measurement associated with a second type of clock in the plurality of clocks, wherein the first type of clock and second type of clock are substantially similar frequencies with respect to one another;
• measuring an error associated with a transmitter according to the chosen calibration mode;
• generating an error detector output based on an output generated in response to a defined data input bit pattern, wherein the defined data input bit pattern is based upon the chosen calibration mode;
• and
• adjusting the first type of clock in the plurality of clocks based on the error detector output.

A method comprising:

• providing a plurality of defined bit patterns to a transmitter;
• converting the defined bit patterns into a plurality of output data streams based upon a clock provided to the transmitter, wherein the converting further comprises
• converting a first one of the plurality of output data streams based on a first clock pattern, wherein the first one of the plurality of output data streams is associated with a first one of the plurality of defined bit patterns, and
• converting a second one of the plurality of output data streams based on a second clock pattern, wherein the second one of the plurality of output data streams is associated with a second one of the plurality of defined bit patterns,
• detecting a plurality of errors for the clock, wherein respective ones of the plurality of errors are associated with respective ones of the plurality of defined bit patterns, wherein the detecting comprises measuring the plurality of errors;
• generating error detection output information, wherein a first portion of the error detection output information is associated with the measuring of a first one of the plurality of errors and a second portion of the error detection output information is associated with the measuring of a second one of the plurality of errors;
• and
• adjusting the clock based on the results of the measuring the plurality of errors, including the first error detection output information and the second error detection information.
