摘要： Additional information on the phase of an external clock signal is obtained by using clock signals to determine if a phase difference between an external clock signal and a first internal sampling clock signal is less than a pre-selected value. If the system determines that the phase difference is less than a pre-selected value, one embodiment samples the incoming data with a second internal sampling clock signal, having a selected phase relationship to the first internal sampling clock signal, such as ½ a clock period out of phase. By maintaining sufficient phase difference between the active edge of the external clock and the active edge of the internal sampling clock, the embodiment provides a sufficient setup/hold margin to avoid a metastability or other problem in a subsystem receiving data across an asynchronous boundary.

摘要： A bidirectional communications interface is provided that connects a transmitter and a receiver, or a transceiver, to a transmission line. Under an embodiment, the bidirectional interface generates positive and negative polarity data signals using two separate differential amplifiers that receive differential signal pairs from each side of a differential link to the transmission line and the transmitter. The bidirectional interface controls common mode rejection in each of the separate differential amplifiers using bias signals generated in response to an output common mode feedback voltage from each of the differential amplifiers. An output amplifier combines the positive and negative polarity data signals to form single-ended output logic signals. The output logic signals represent data received on the transmission line, and are provided to the receiver.

摘要： A scheme for reducing jitter in high-speed digital communication by adaptively controlling the loop bandwidth of a receiver PLL to reduce the relative jitter between the recovered data and clock. The scheme uses phase pointer activity to represent the relative jitter. The phase pointer activity is measured and used to control the receiver PLL loop bandwidth. The receiver PLL loop bandwidth is repeatedly incremented or decremented by a step size based on the comparison between a newly measured activity value and the old activity value, until the phase pointer activity reaches a minimum. Because the PLL performance requirement of the transmitter can be relaxed, compatibility with legacy transmitters and multi-vendor transmitters is enhanced. Because tight control of fabrication process parameters of PLLs may be relaxed, the fabrication yield may also be improved.
