    摘要: Described are systems and apparatuses to mitigate the timing margin loss caused by inter-symbol interference (ISI) in high speed input/output (I/O) interfaces. Data dependent jitter (DDJ) compensation techniques that may be utilized in the transmission or receiving circuitry of the I/O interface, including capturing bit data values of a data signal prior to an identified data transition, and delaying/advancing the transmission/reception the data signal or a corresponding clock signal based on these bit data values.

    摘要: In one embodiment, the present invention includes a method for receiving a jitter profile and a step response of a channel coupled between a transmitter and a receiver and a bit pattern to be transmitted, transmitting the bit pattern along the channel from the transmitter to the receiver with the jitter profile and the step response, receiving the bit pattern at the receiver and converting the bit pattern to a data stream by interpolating the step response according to a jitter of a current bit to obtain a jittery step response, superposing the jittery step response onto the data stream, calculating the jitter at each transition bit of the bit pattern by determining a time difference between actual and ideal crossing points, incrementing a jitter distribution function with the jitter, and generating a timing curve for the channel using the jitter distribution function. Other embodiments are described and claimed.
