Abstract
At least one exemplary embodiment of the present invention includes a method for compensating for delays in a circuit of a serial encoder. The method includes determining at least one delay associated with the circuit of the serial encoder. The method also includes adjusting an internal clock signal received by a data receiving memory associated with the serial encoder to account for the at least one determined delay.
