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.

摘要： A signal history controlled slew-rate transmission method and bus interface transmitter provide an improved channel equalization mechanism having low complexity. A variable slew-rate feed-forward pre-emphasis circuit changes the slew rate of the applied pre-emphasis in conformity with the history of the transmitted signal. The pre-emphasis circuit may be implemented by a pair of current sources supplying the output of the transmitter, and having differing current values. The current sources are controlled such that upon a signal value change, a high slew rate is provided and when the signal value does not change for two consecutive signal periods, the slew rate is reduced. A current source having a controlled magnitude may be employed to provide a slew rate that changes over time and is continuously reduced until another transmission value change occurs.

摘要： The on-chip power supply noise sensor detects high frequency overshoots and undershoots of the power supply voltage. By creating two identical current sources and attaching a time constant circuit to only one, the high frequency transient behavior differs while the low frequency behavior is equivalent. By comparing these currents, the magnitude of very high frequency power supply noise can be sensed and used to either set latches or add to a digital counter. This has the advantage of directly sensing the power supply noise in a manner that does not require calibration. Also, since the sensor requires only one power supply, it can be used anywhere on a chip. Finally, it filters out any lower frequency noise that is not interesting to the circuit designer and can be tuned to detect down to whatever frequency is needed.

摘要： A system for transmitting and receiving data between the near end to the far end of a transmission line. The system has simultaneous bi-directional (SBIDI) drivers and receivers for high performance over well behaved transmission lines. The SBIDI drivers and SBIDI receivers are enabled and disabled by logic inputs. A unidirectional (UNI) receiver is connected in parallel with each SBIDI receivers. Logic insures that the SBIDI and UNI receivers are not enabled at the same time. When desired, the SBIDI receivers are disabled and the UNI receivers enabled and signaling is done unidirectional. The current level in the SBIDI drivers may be modified in response to mode compensation signals to improve signal to noise in the unidirectional mode and to compensate for losses in the simultaneous bi-directional mode. The system may be integrated into all I/O's for maximum design flexibility.

摘要： A serial communication interface for sending and receiving serial data is provided including a serializer and a deserializer.The serializer is designed so that the serializer VCO has a center frequency that is one half the center frequency of the deserializer VCO. The serializer uses both edges of the clock to mix the serial bits. The deserializer design is unchanged. The two VCO's are implemented on separate chips with both chips located on the same metallized ceramic substrate with a ground plane about 40 mm apart. Near frequency interaction is significantly reduced.

摘要： A calibratable communications link includes multiple parallel lines. Calibration is performed at dynamically variable and/or interruptible intervals determined by an automated mechanism. Calibration is preferably initiated responsive to a command generated by an executable software process, which initiates calibration responsive to detection of a probable impending need as indicated by, e.g., temperature change, calibrated parameter drift, error rate, etc. Calibration is also preferably initiated according to probable minimal disruption of device function, as indicated by low activity level. Furthermore, in one aspect calibration may be temporarily suspended to transmit data and then resumed.
