| 1. An integrated circuit for use in a transceiver module, the integrated circuit comprising:
a first electrical input port for receiving a first serial electrical data stream;
receiver eye opener circuitry for retiming and reshaping the first serial electrical data stream;
a first electrical output port for transmitting the retimed and reshaped first serial electrical data stream to external to
the integrated circuit;
receiver bypass circuitry for switchably selecting, based on a data rate of the first electrical data stream, a bypass data
path from the first electrical input port to the first electrical output port to bypass retiming and reshaping of the first
serial electrical data stream;
a second electrical input port for receiving a second serial electrical data stream from external to the integrated circuit;
transmitter eye opener circuitry for retiming and reshaping the second serial electrical data stream; and
a second electrical output port for transmitting the retimed and reshaped second serial electrical data stream.
