发明名称 Circuit and method for adjusting timing alignment using programmable codes
摘要 A method is provided for adjusting timing alignment in which a receiver generates a plurality of imbalanced correction codes ( 1310 ), and square waves both having the same frequency. The receiver mixes the imbalanced correction codes with the square waves to create a mixed signal ( 1320 ), and integrates the mixed signal over a correction code period to generate a signal power value ( 1330 ). The receiver adjusts a phase of the square wave in a first direction when the signal power value satisfies a first criterion ( 1340, 1350 ), and in a second direction when the signal power value satisfies a second criterion ( 1340, 1360 ). Each imbalanced correction code is symmetrical. And a total integrated value of one of the imbalanced correction codes over the correction code period is either above a first threshold, or below a second threshold, the first threshold being greater than or equal to the second threshold.
