摘要： An interface for implementing a loopback configuration which offers improved calibration and/or testing of an electronic system is disclosed. More specifically, embodiments provide a bi-directional interface with at least two portions or partitions capable of communicating data in opposite directions and implementing a loopback configuration between components of an electronic system, thereby enabling more flexible, efficient and effective calibration and/or testing of the electronic system using a single interface. The loopback of the partitioned bi-directional interface may be used to perform data link training and/or electronic system testing. In one embodiment, the loopback configuration of the interface may be reversible. Additionally, the looped or coupled end of the partitions may be switched from one component to another, thereby reversing the configuration of the loopback in one embodiment. As such, embodiments enable different and/or additional calibration operations and/or tests to be performed when compared with conventional loopback configurations.

摘要： A method of receiving data. A plurality of data signals and clocking signals are received over a source synchronous communication channel. The plurality of data signals is strobed with the clocking signal at a plurality of coarse time offset delays (e.g., time offset delays spanning over a data bit period). The plurality of error rates associated with the strobing at the plurality of coarse time offset delays is determined. Strobing design of a transmitting component (e.g., edge-strobed, center-strobed, etc.) may be determined based on the plurality of error rates. The error rates of the plurality of data signals strobed with a plurality of time offset delays close to the determined strobing design of the transmitting component is calculated. A time offset delay is selected based on the error rates. The plurality of data signals can be strobed with the selected time offset delay to recover the transmitted data signals.

摘要： In a video system in which a video signal source transmits a video signal to a receiver over a transmission line, a method of maintaining a desired voltage level from the video signal source includes the steps of monitoring the level of voltage at the output of the video signal source, and adjusting an input to the video signal source as necessary in order to maintain a desired level of voltage. Thus, when the impedance of the transmission line and receiver change, the output voltage from the video signal source is maintained at a desired level without clipping of the signal when the video signal source is overdriven.
