    摘要: A differential data strobe receiver is provided which is configured to receive a differential data strobe signal at a first strobe input and a second strobe input, wherein transitions of the differential data strobe signal indicate sample points for an associated data signal. The differential data receiver is configured to identify the transitions of the differential strobe signal by differentially comparing values of the differential strobe signal received at the first strobe input and the second strobe input. The differential data strobe receiver comprises strobe gating circuitry configured to generate a strobe gating signal, wherein the associated data signal can only be sampled in dependence on the differential data strobe signal when the strobe gating signal is asserted and strobe input termination circuitry configured selectively to provide a first termination connection for the first strobe input and a second termination connection for the second strobe input. The differential data strobe receiver is configured, prior to receiving the differential data strobe signal in association with the associated data signal, to participate in an initial gate training process to determine a gating delay used to phase align the strobe gating signal with respect to the differential data strobe signal and the strobe input termination circuitry is configured to provide an asymmetric configuration of the first termination connection and the second termination connection during the initial gate training process.

    摘要: A differential receiver having a pair of cross-coupled signal conditioning devices improves transition time and data signal integrity. In an embodiment, the differential receiver includes two signal input nodes and a plurality of transistors, and two signal output nodes. The pair of cross-coupled signal conditioning devices are coupled to the transistors and function to reduce voltage swing between the two output nodes, thereby keeping the transistors in a saturation region.
