Minimum latency propagation of variable pulse width signals across clock domains with variable frequencies

摘要

An apparatus comprising a counter circuit, a first register circuit, a second register circuit and an output circuit. The counter circuit may be configured to generate a count signal in response to a data input signal and a first clock signal operating in a first clock domain. The first register circuit may be configured to generate a first control signal in response to the count signal. The second register circuit may be configured to generate a second control signal in response to the data input signal. The output circuit may be configured to generate a data output signal operating in a second clock domain in response to the first control signal, the second control signal, the count signal, and a second clock signal.
