摘要： Pseudo-differential drivers and receivers are used to communicate data signals between two or more IC chips. The data paths are aligned using programmable delay circuitry to de-skew each data path. A programmable reference generator is used to generate a reference voltage used by one or a group of receivers to detect the data signals. The reference voltage is adjustable using coarse as well as fine digitally controlled voltage increments. Test signals are sent from the driver to the receiver and the reference voltage is varied over its adjustable range using the coarse and fine adjustment controls while circuitry determines a measure of the detection timing jitter on successive transitions of the test signal. The operational value of the reference voltage is set to the value where the detection timing jitter is determined to be a minimum.

摘要： Shadow selection logic is used to select a driver bit position as a shadowed driver value, and line drivers to transmit data for the selected driver bit position and the shadowed driver value on separate link segments of a bus. In addition shadow compare logic is used to compare a selected received value with a shadowed received value from the bus and identify a miscompare in response to a mismatch of the compare, and shadow counters to count a rate of the miscompare relative to a bus error rate over a period of time. A defective link segment is identified in response to the rate of the miscompare within a predefined threshold of the bus error rate.

摘要： A mechanism for de-skewing and aligning data bits sent between two chips on an elastic interface. On the receiving end of an elastic interface, the eye of each data bit within a clock/data group is delayed by less than a bit time to align the eyes with the nearest clock edge of a received clock signal. In addition to aligning the eyes of the individual data bits with the nearest clock edge, IAP patterns are used to determine the amount of further delay needed to line up the individual data beats from each data bit. If the data beats for the data bits are not aligned, all but the slowest data beat are delayed to align the data beats for all bits. The additional delay is achieved using sample latches that result in a delayed signal with less jitter. As a result of having less jitter, the received, de-skewed, and aligned clock/data group can be forwarded to the operative portion of the receiving chip at an increased frequency.

摘要： A method and apparatus for de-skewing and aligning digital data received over an elastic interface bus is disclosed. Upon receiving the data, it is sent through a programmable delay line. While in the programmable delay line, the data is sampled at three points within the data's eye pattern. The three sampling points are dynamically adjusted to maximize coverage of the data's eye pattern. During the adjustment of the sampling points to optimally cover the data's eye pattern, delayed data is sampled from an alternate sampler to prevent sampling from the functional sampler while the delay in the primary sampler is adjusted. Sampling from the alternate sampler while changing the sampling points of the functional sampler serves to reduce glitches that may occur by sampling the functional sampler while its sampling parameters are changed. The method and apparatus allow for alternate eye tracking and wrap around eye tracking.
