Abstract:
1. An information transmission link comprising: a transition minimized differential signaling encoder coupled to receive digital data from a plurality of parallel lines to encode the digital data into encoded digital data; a serializer coupled to receive the encoded digital data from the encoder through a plurality of parallel lines to serialize the encoded digital data into encoded and serial digital data; a pseudo-random binary sequence generator circuit to generate test data; a multiplexer coupled to receive the encoded and serial digital data from a first line coupled to the serializer and the test data from a second line coupled to the sequence generator circuit, the multiplexer to transmit the encoded and serial digital data to a transmission medium in a normal mode of operation and being coupled to receive a test signal to put the multiplexer in a test mode of operation to transmit the test data to the transmission medium; and wherein the encoder, the serializer, the sequence generator circuit, and the multiplexer are fabricated in a single integrated circuit chip.
