Transceiver module and integrated circuit with clock and data recovery clock diplexing

摘要

An integrated circuit. The integrated circuit is usable in a transceiver module. The integrated circuit includes an input port that is configured to receive a data stream. A clock port on the integrated circuit is configured to receive a reference clock diplexed with another signal or voltage used by the integrated circuit. An eye opening circuit is connected to the input port and clock. The eye opening circuit is configured to retime the data stream received at the input port. An output port is connected to the eye opening circuits The output port is configured to transmit a retimed signal from the eye opening circuit to a device external to the integrated circuit. A bypass circuit is connected to the input port and the output port. The bypass circuit may selectively bypass the eye opening circuit.
