摘要：A method for aligning output from a first transmit source and a second transmit source is provided. The method includes combining complementary portions of differential signals generated from respective transmit sources to generate an output bit sequence and comparing the output bit sequence with an input bit sequence used to generate the differential signals. The method further includes adjusting one of the first or the second transmit source based on the comparison to align the output from the first and the second transmit sources. A PLD having the capability to align channels of different octets is also provided.
