摘要： Methods, apparatuses and systems for physical link error data capture and analysis. A receiver is coupled to receive a data stream via a point-to-point serial link. A control circuit is coupled with the receiver to cause the receiver to selectively sample the data stream according to an offset parameter and an interval parameter. Comparison circuitry compares the data stream sample to expected data values to determine a bit error rate.

摘要： A condition is detected to cause a component having physical layer circuitry with a transmitter and a receiver to enter a testing state. The transmitter transmits a pre-selected data pattern while comparing data received by the receiver to the pre-selected data pattern during a first phase of the testing state. The transmitter transmits data received by the receiver without comparing the data received by the receiver to the pre-selected data pattern during a second phase of the testing state.

摘要： In general, in one aspect, the disclosure describes an apparatus having an averager to receive differential output voltages of a transmitter and generate an average transmitter output voltage. A comparator is to compare the average transmitter output voltage to a reference voltage and generate a difference therebetween. An integrator is to integrate the difference between the average transmitter output voltage and the reference voltage over time. The integrated difference is fed back to the transmitter to bias the transmitter.
