Abstract
An embodiment of a multiplexer circuit may include a plurality of PTOTAL receive (RX) channel outputs and a plurality of QTOTAL pins, where QTOTAL is greater than PTOTAL. Each of a first subset and a third subset of the plurality of QTOTAL pins may be switchably coupled to at least one of the plurality of RX channels, each of a second subset of the plurality of QTOTAL pins is switchably coupled to two of the plurality of RX channels, and for each possible subset of PTOTAL contiguous pins from the plurality of QTOTAL pins, each pin in the possible subset may be switchably coupled to a different RX channel output of the plurality of RX channel outputs.
