摘要： A system and method is provided for phase interpolator based transmission clock control. The system includes a transmitter having a phase interpolator coupled to a master timing generator and a transmission module. The phase interpolator is also coupled to a receiver interpolator control module and/or an external interpolator control module. When the system is operating in repeat mode, the transmitter phase interpolator receives a control signal from a receiver interpolator control module. The transmitter phase interpolator uses the signal to synchronize the transmission clock to the sampling clock. When the system is operating in test mode, a user defines a transmission data profile in an external interpolator control module. The external interpolator control module generates a control signal based on the profile. The transmitter phase interpolator uses the signal to generate a transmission clock that is used by the transmission module to generate a data stream having the desired profile.

摘要： Various systems and methods related to equalization precoding in a communications channel are disclosed. In one implementation precoding is performed on signals transmitted over an optical channel. In one implementation precoding and decoding operations are performed in parallel to facilitate high speed processing in relatively low cost circuits. Initialization of the precoders may be realized by transmitting information related to the characteristics of the channel between transceiver pairs.

摘要： A voltage supply interface provides both coarse and fine current control with reduced series resistance. The voltage supply interface has a segmented switch having N component switches that are digitally controlled. The voltage supply interface replaces a conventional sense resistor with a calibration circuit that has a replica switch that is a replica of the N component switches. The calibration circuit includes a reference current IREF that is sourced through the replica switch. A voltage comparator forces a common voltage drop across the replica switch and the n-of-N activated component switches so that the cumulative current draw through the segmented switch is n·IREF. The current control of the voltage interface can be coarsely tuned by activating or deactivating component switches, and can be finely tuned by adjusting the reference current. The current sense resistor is eliminated so that the overall series resistance is lower.

摘要： Power over Ethernet (PoE) communication systems provide power and data communications over the same communications link, where a power source device (PSE) provides DC power (for example, 48 volts DC) to a powered device (PD). The DC power is transmitted simultaneously over the same communications medium with the high speed data from one node to the other node. The PSE typically includes a controller that controls the DC power provided to the PD at the second node of the communications link. The PSE controller measures the voltage, current, and temperature of the outgoing and incoming DC supply lines to characterize the power requirements of the PD. In addition, the PSE controller may detect and validate a compatible PD, determine a power classification signature for the validated PD, supply power to the PD, monitor the power, and reduce or remove the power from the PD when the power is no longer requested or required. During detection, if the PSE finds the PD to be non-compatible, the PSE can prevent the application of power to that PD device, protecting the PD from possible damage.

The PSE controller also monitors for a Maintain Power Signature (MPS). The PSE controller removes power from the PD if the MPS condition is absent for longer than its related time limit. The MPS consists of two components: an AC MPS component and a DC MPS component. The PSE controller may optionally monitor the AC MPS component only, the DC MPS component only or both the AC and the DC MPS components.

摘要： Inter-device adaptable interfacing clock skewing. The invention is operable in either one of both of a transmit mode and a receive mode to perform skewing of a transmitted and/or a received signal. The operational parameters including frequency and phase may be determined during auto detect/auto negotiation, they may be programmed externally, or they may be user selected in various embodiments. A device may include a clock generator, one or more divider, and one or more delay cells internally to the device. If desired, a high frequency clock is generated within the device and then divided down to generate the appropriate clock signal that supports the communication and interaction between multiple devices. Registers and/or pins may be used to select the clock frequency and phase of output clock signals. The present invention supports multiple Ethernet protocols between multiple devices including 10BaseT, 100BaseT, and 1000BaseT.
