  • Patent number: 7646839
    Abstract: A unified, unidirectional serial link is described for providing data across wired media, such as a chip-to chip or a card-to-card interconnect. It consists of a transmit section and a receive section that are operated as pairs to allow the serial data communication. The serial link is implemented as part of a VLSI ASIC module and derives its power, data and clocking requirements from the host modules. The logic transmitter portion contains a phase locked loop (PLL), a dibit data register, a finite impulse response (FIR) filter and a transmit data register. The phase locked loop comprises both a digital coarse loop and an analog fine loop. The digital receiver portion contains a PLL, an FIR phase rotator, a phase rotator control state machine, and a clock buffer. The transmitter and the receiver each preferably utilize a pseudo-random bit stream (PRBS) generator and checker.

  • Patent number: 7539243
    Abstract: A method and system for decision feedback equalization for digital transmission systems is provided. Low-power integrating decision feedback equalization with fast switched-capacitor paths are used, for suppressing intersymbol interference (ISI) due to past data symbols. The decision feedback equalization involves performing current-integrating decision feedback equalization at low-power employing a fast capacitively coupled feed-forward path at the output of a current-integrating buffer and inducing voltage changes by charge redistribution via coupled switching capacitors, and performing a voltage digital-to-analog conversation to determine a feedback coefficient as a coupling voltage. Then switches are reset to a pre-charge coupling voltage in the buffers to eliminate residual ISI caused by signal history, thereby achieving current integrating buffering with switched-capacitor feedback during the integration, and the capacitive switches are triggered by previous symbols.

  • Publication number: 20080285695
    Abstract: Methods and arrangements to determine phase adjustments for a sampling clock of a clock and data recovery (CDR) loop based upon subsets of data samples, or values, derived from an incoming data signal are disclosed. In particular, embodiments extend the CDR loop by slowing the clock rate with respect to the sampling clock. For instance, the slower clock rate may be implemented by dividing the frequency of the sampling clock by a number such as 128, slowing a sampling clock frequency designed to handle multiple gigabits per second (Gbps) to a frequency of less than one kilohertz (Khz). In addition to the reduced power consumption realized by operating at a lower frequency, the slower clock rate allows components of the CDR loop circuitry to operate a lower operating voltage reducing power consumption by the CDR loop even more.
