Abstract
A gating signal for masking overhead transitions in a data-strobe signal is generated adaptively based on timing events in the incoming data-strobe signal itself to yield a gating window that opens and closes deterministically with respect to active edges of the data-strobe signal.
Claims20
A method of operation within an integrated-circuit component, the method comprising:
- receiving, via an external timing signal link, a first timing signal having a sequence of data-timing transitions preceded by one or more preamble transitions and succeeded by one or more postamble transitions;
- generating a gating pulse having a time-varying pulse width according to a time-varying skew between the first timing signal and an internal timing domain of the integrated-circuit component;
- and
- logically combining the gating pulse with the first timing signal to produce a gated timing signal that lacks the one or more preamble transitions and the one or more postamble transitions.

An integrated-circuit component comprising:
- a timing input to receive a first timing signal having a sequence of data-timing transitions preceded by one or more preamble transitions and succeeded by one or more postamble transitions;
- and
- gating circuitry to:
- generate a gating pulse having a time-varying pulse width according to a time-varying skew between the first timing signal and an internal timing domain of the integrated-circuit component;
- and
- logically combine the gating pulse with the first timing signal to produce a gated timing signal that lacks the one or more preamble transitions and the one or more postamble transitions.
