    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: An integrated processor design includes physical interface macros supporting heterogeneous electrical properties. The processor design comprises a plurality of processing cores and a plurality of physical interfaces to connect to a memory interface, a peripheral component interconnect express (PCI Express or PCIe) interface for input/output, an Ethernet interface for network communication, and/or a serial attached SCSI (SAS) interface for storage. Each physical interface may be programmatically connected to a selected interface controller, such as a memory controller, a PCI Express controller, or an Ethernet controller, for example. A plurality of such controllers may be connected to a switch within the processor design, with the switch also being connected to each physical interface macro. Thus, the physical interface macros may be programmatically connected to a subset of the plurality of controllers.

    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 line driver for off-chip communication comprises multiple parallel stages each with separate inputs. The parallel stages each have a controlled impedance when driving the line driver output node to a logic zero or a logic one. A line driver controller is used to select what combination of driver stages are used to drive the output node based on whether the output node is transitioning between logic state or is remaining static. During power-up, a test program tries different combinations of driver stages for particular symbol patterns and determines what is the optimal ratio between line driver resistance for the dynamic and static cases and stores the optimum combination. The data stream feeding the line driver is sampled in real time to determine the transition states and selects the optimal number of driver stages for each case.

    摘要: Two or more integrated circuit (IC) chips are separated by a significant distance relative to their communication frequency such that pseudo-differential signaling is used to improve signal detection. A derived reference voltage is generated that tracks the variations of the driver and receiver side power supply variations that normally reduce noise margins. The derived reference voltage is filtered to reduce high frequency response and coupled as the reference to differential receivers used to detect the logic levels of the communication signals.
