An apparatus for testing a transducer module includes a test signal generator coupled to a common-mode terminal common to a plurality of transducers, and a signal processing circuit configured to receive output signal from each of said transducers and to produce an output signal. If the transducers are well matched to one another, the output signal will have little or no output amplitude. If there is a mismatch between the transducers, however, the output signal will have an amplitude proportional to the mismatch. The amplitude of the output signal may be compared to a predetermined threshold in order to produce a mismatch output signal indicating the existence of, and/or the degree of, mismatch between the transducers.

One or more link training signals are received, including instances of a link training pattern, on a plurality of lanes of a physical link that includes at least one valid lane and a plurality of data lanes. The plurality of lanes are trained together using the link training signals to synchronize sampling of the valid lane with sampling of the plurality of data lanes. An active link state is entered and a valid signal received on the valid lane during the active link state. The valid signal includes a signal held at a value for a defined first duration and indicates that data is to be received on the plurality of data lanes in a second defined duration subsequent to the first duration. The data is to be received, during the active link state, on the plurality of data lanes during the second defined duration.
