    摘要: A system includes a master device connected to one or more slave devices via a channel, the channel communicating an externally generated first system clock towards the master device. A delay locked loop circuit receives the first system clock and a second phase feedback signal as inputs and generates a transmit clock signal. A phase offset circuit receives the transmit system clock and generates a phase shifted version of the transmit clock signal as a second system clock. A first phase detector receives a receive system clock and the transmit system clock and generates a first phase feedback signal. A delay element receives the first system clock and the first phase feedback signal and generates a delayed first system clock. A second phase detector receives the delayed first system clock and the second system clock and generates the second phase feedback signal.

    摘要: A circuit for clocking includes an input data path, a receiver, a set of flip-flops, at least one interpolator and a controller. The receiver is coupled to the input data path for receiving input data. The flip-flops, coupled to the receiver, sample the input data. A first interpolator, coupled to one or more of the flip-flops, receives the sampled input data. The controller, coupled to the first interpolator, controls the first interpolator by providing phase information regarding the input data to the first interpolator. The circuit reduces any jitter transferred from the input path to an output path.

    摘要: Transmitter waveform dispersion penalty (“TWDP”) is decreased in a transmitter. A binary data signal is received for transmission over a channel that exhibits TWDP. The data signal is shifted less than a full clock cycle to generate at least one post cursor signal. The post cursor signal is subtracted from the data signal to generate a transmitter output data signal for transmission over the channel. In addition to decreasing TWDP, data dependent jitter is also reduced for data transmission across a channel that exhibits a multi-pole transmission characteristic. A main data signal and at least one cursor signal, which is shifted at least a portion of a clock period from the main data signal, is generated. The cursor signal is filtered to filter out effects based on the second pole of the multi-pole transmission characteristic. The main data signal is subtracted from the filtered cursor signal to generate the transmitter output data signal. Circuits and methods for transmitting serial data streams over a channel compliant with KR and SPI specifications are also disclosed.

    摘要: Methods and circuits provide function-appropriate signaling to multi-functional circuits on a constrained set of communication lines. A first communication line receives digital signals. The second communication line is employed for digital signaling related to a first function. In further steps, the method comprises initiating, based on a multi-value logic digital signal on the first communication line, an activation process that generates a second-function activation signal. Upon receipt of the second-function activation signal, the second communication line is employed for digital signaling related to a second function. Preferred activation processes involve monitoring the second communication line for a digital signature and sending the activation signal upon detection of an appropriate signature.
