Abstract: The present invention relates to analogue-to-digital converter circuitry, and in particular to alignment between one set of analogue-to-digital circuitry and another set. Such sets may be referred to as converter channels.

Abstract: A clock recovery circuit includes a demodulator which generates in-phase and quadrature signals from a data signal and a phase adjuster which adjusts a phase of the quadrature signal independently from a phase of the in-phase clock signal. The phase adjustment causes a non-orthogonal relationship to exist between the phases of the quadrature and in-phase signals. The independent phase adjustment may be dynamically performed or may be performed in fixed increments to achieve a predetermined level of performance. In one application, the adjusted quadrature phase signal serves as a clock signal for controlling sampling of the data signal.

Abstract: A system and method of evaluating transmission errors in data received at a sink device are described. The sink device may receive a test data sequence on each of a plurality of data lanes and detect transmission errors associated with specific data lanes. The sink device may then output data representative of at least some of the detected transmission errors in association with at least one of a data interval and a data lane.
