    摘要: A receiver for a serial link port that is enhanced by a clock-data-recovery loop connected to the forwarded clock signal lane. The receiver includes a phase interpolation means controlled by a phase position logic which gets its update signal from local phase update signals of the clock-data-recovery loop via a digital low pass filter. The receiver also provides a global phase update source selection logic to control which clock-data-recovery loop is distributing phase update information, and which clock-data-recovery loop is receiving phase update information based on the clock analysis block.

    摘要: 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.

    摘要: 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.
