Certain pins of an XFP connector are re-purposed to enable the connector to receive, for example, four 11.88 Gb/s serial data streams (for a receiver), or output four 11.88 Gb/s serial data streams (for a transmitter). The four data streams are wavelength division multiplexed inside the XFP module for transmission over a single optical fiber, providing a total interface capacity of 47.52 Gb/s. An XFP receiver module is defined to convert the WDM signal back to four 11.88 Gb/s serial data streams.

Systems and methods are provided for reducing pathological conditions in a serial video interface. A sequence of parallel data words that are to be transformed by a data-scrambling algorithm comprise an input signal. The bit order of one or more of the words in the sequence of parallel data words is reversed and the sequence of parallel data words, now including one or more bit-reversed words, is transmitted. The signal resulting from application of a data-scrambling algorithm to the sequence of parallel data words, including one or more bit-reversed words, has a reduced likelihood of including a pathological condition.

An auto-configurable video deserializer with embedded audio support includes a video core, a clock generator and an audio core. The video core receives a serial video signal of an unknown video standard, converts the serial video signal into a parallel video signal, and decodes the parallel video signal to identify the unknown video standard and generate one or more auto-configuration signals. The clock generator generates an audio clock signal. The audio core is coupled to the video core and the clock generator, and receives the parallel video signal and one or more auto-configuration signals from the video core and receives the audio clock signal from the clock generator. The audio core uses the auto-configuration signal(s) to automatically locate and extract audio data from within ancillary space of the parallel video signal and synchronizes the extracted audio data with the audio clock signal to generate an audio output signal.
