ABSTRACT:
A differential clock signal gating method and system is provided, wherein a clock buffer circuit control path develops a clock gating signal with a timing relationship to a clock signal. The clock gating signal gates a buffer on the clock buffer circuit controlled path in communication with the clock signal responsive to a first clock signal pulse negative half. The buffer provides second and successive clock signal pulses occurring immediately and sequentially after the first clock signal pulse as a buffer clock signal output to a second buffer stage in a second stage clock path, each having the nominal clock amplitude and the nominal clock pulse width of the clock signal without jitter.
