摘要： A method is presented that monitors the quality of a communications channel. The method includes receiving a data signal and establishing a zero reference phase of the received data signal. The method further includes generating a phase-shifted data signal by phase shifting the received data signal relative to the zero reference phase, and sampling the phase-shifted data signal for one or more phase-shift positions. A zero reference phase is reestablished between sampling at each of the phase-shift positions. The method also includes detecting bit errors in the phase-shifted data signal at each of the phase-shift positions in order to provide a communications channel quality measurement. In an embodiment, the method includes generating an eye diagram according to a count of detected bit errors relative to a count of detected bits. The eye diagram characterizes the quality of the communications channel.

摘要： A system is presented that monitors the quality of a communications channel with mirror receivers. A first receiver and a second receiver, coupled in parallel with the first receiver, receive a data signal transmitted over the communications channel. The second receiver generates an output signal. A signal integrity (SI) processor manipulates the output signal in order to determine the quality of the communications channel. The SI processor samples a phase-shifted version of the output signal, which has a phase shifted relative to a zero reference phase, and analyzes the phase-shifted version of the output signal for bit errors. In an embodiment, the SI processor manipulates the output signal to extract an eye diagram indicative of the quality of the communications channel. The SI processor non-intrusively determines the quality of the communications channel using the second receiver.

摘要： Certain aspects of the method may comprise receiving via a first port of the port bypass controller, a data stream comprising at least one known bit pattern. Upon locking onto at least a portion of the known bit pattern in the received data stream, a bit error rate may be generated based on a bit-by-bit comparison of at least a portion of the data stream received after locking occurs. At least a portion of the data stream may be compared with a corresponding portion of expected data. The bit error rate may be calculated based on results from comparing at least a portion of the data stream with a corresponding portion of the expected data. The known bit pattern may be internally generated within the port bypass controller or it may be externally generated by a host system.
