Abstract: A network monitor may execute, or communicate with, one or more stored machine learning models that are trained to predict a failure probability for one or more ports and/or links within a network fabric. Systems and methods may monitor a set of ports and/or links to generate predictions for failure probabilities using a first trained model and low frequency telemetry data. For a subset of ports and/or links with failure probabilities exceeding a first threshold, high speed telemetry data may be used by a second trained model to generate predictions for failure probabilities for the subset of ports. Suspicious ports may then be isolated and undergo various remediation and/or monitoring actions prior to de-isolating the isolated ports.

Abstract: Methods and apparatuses for clock signal phase measurement and control are described. In one example, a clock signal phase measurement system includes a reference clock signal line to provide a reference clock signal, a delay line to provide an output clock signal, and a wild clock. The clock signal phase measurement system includes a phase sensor configured to randomly and simultaneously sample the reference clock signal and the output clock signal utilizing the wild clock to obtain a phase data. The phase sensor is further configured to measure from the phase data a phase difference between the reference clock signal and the output clock signal.

Abstract: A data transmitter high side switch includes at least one output unit, an input logic unit, a reset circuit coupled to the input logic unit, a capacitor pump circuit coupled to the reset circuit and the input logic circuit, and operatively to the at least one output unit. The capacitor pump circuit includes at least one capacitor that is charged in a first direction during a time period when the input data signal is in a first logic level. During a subsequent time period, when the input data signal is in a second logic level, a reference voltage for the charge on the capacitor is changed to thereby provide an overdrive level turn-on voltage to a corresponding output transistor of the at least one output unit. The charge of the at least one capacitor can be adjustably selected to compensate for tolerance variations and/or ambient conditions to control output impedance.
