    摘要: A communications system that may include a transmitter, a receiver, connected over a communications network. A communication link on the communications network may transfer data between the transmitter and the receiver. The system may also include a logic unit to scramble a plurality of portions of the data at the transmitter based upon the communication link and may unscramble the plurality of portions of the data at the receiver. As a result, the logic unit may provide improved performance of the communication link and/or reduced power consumption of the communication link.

    摘要: A design structure is provided for a reference voltage generator. The design structure includes a first capacitor and an analog to digital converter having its voltage reference coupled to the first capacitor. The first capacitor supplies the voltage reference to the analog to digital converter. A control loop is configured to resupply charges to the first capacitor that are lost when the first capacitor supplies the voltage reference to the analog to digital converter.

    摘要: A high-speed receiver includes multiple receiver components. Each receiver component includes sampling latches for receiving data, phase rotators for controlling timing of sampling of data by the sampling latches, and a clock-tracking logic stage for providing clock and data recovery. The clock-tracking logic stage is divided into a high-speed early/late (E/L) logic and aggregation counter section and a low-speed logic section, separated by a synchronization logic block. The receiver also includes a delay locked loop (DLL) for receiving an input clock signal corresponding to a data rate of the received data, providing coarse delay adjustment of the clock signal and outputting multiple clock phase vectors corresponding to the adjusted clock signal to the phase rotators on each receiver component. The phase rotators control sampling of the data based on the clock phase vectors received from the DLL. A single regulated power supply regulator regulates power supplied to the DLL and the phase rotators.

    摘要: Jitter method and control circuit for a circuit block in a transceiver system having a phase lock loop circuit which includes an oscillator, a charge pump connected to the oscillator to add or subtract charge to or from said oscillator, and a low pass filter connected to said charge pump are provided. Circuitry is connected to the output of the oscillator and the input of the charge pump to control the amount of charge added to or subtracted from the charge pump to control the bandwidth output by the oscillator and thereby reduce jitter in the phase lock circuit.

    摘要: A communication interface device, system, method, and design structure for error correcting code (ECC) protected quasi-static bit communication (SBC) on a high-speed bus are provided. The communication interface device includes high-speed sampling logic to capture high-speed data from the high-speed bus using a high-speed sampling clock and SBC sampling logic to capture SBC samples from the high-speed bus using an SBC sampling clock. The SBC sampling clock is slower than the high-speed sampling clock. The communication interface device also includes an SBC finite state machine (FSM) to detect a received SBC command in response to a static pattern persisting for a predetermined number of the SBC samples and command decoding logic to decode the received SBC command.
