Serializing transmitter

摘要

In embodiments of a serializing transmitter, the serializing transmitter includes N multiplexing drive units, each configured to generate a series of output pulses derived from input data signals and multi-phase clock signals, and each multiplexing drive unit including a pulse-controlled push-pull output driver having first and second inputs and an output. Each multiplexing driver unit further includes a first M:1 pulse-generating multiplexer having an output coupled to the first input of the pulse-controlled push-pull output driver, and a second M:1 pulse-generating multiplexer having an output coupled to the second input of the pulse-controlled push-pull output driver, wherein each of the first and second M:1 pulse-generating multiplexers has three or fewer gate delays from a clock input to an output of the pulse-generating multiplexer.

1. A serializing transmitter, comprising:
N multiplexing drive units, each configured to generate a series of output pulses derived from input data signals and multi-phase clock signals, wherein N is a positive integer, and wherein each multiplexing drive unit includes
a pulse-controlled push-pull output driver having first and second inputs and an output,a first M:1 pulse-generating multiplexer having an output coupled to the first input of the pulse-controlled push-pull output driver and configured to generate a first series of intermediate pulses having a first pulse width at said output, where M is two or more, anda second M:1 pulse-generating multiplexer having an output coupled to the second input of the pulse-controlled push-pull output driver and configured to generate a second series of intermediate pulses having a second pulse width at said output,wherein each of the first and second M:1 pulse-generating multiplexers has three or fewer gate delays from a clock input corresponding to each of the multi-phase clock signals to an output of the respective pulse-generating multiplexer.
