    摘要: A phase-locked loop (PLL) having a bias generator capable of reducing noise is provided. In the PLL, a voltage controlled oscillator is driven using a regulator. The bias generator, which applies a bias voltage to the regulator, is configured to have opposite power noise characteristics to the power noise characteristics of the regulator, such that the occurrence of jitter in the PLL is reduced.

    摘要: A data communication device or system includes a preamble unit and a data interface. The preamble unit generates or detects a first preamble having a first length for a first data line, and generates or detects a second preamble having a second length for a second data line. The first length is different from the second length, and data on the first and second data lines form parallel data. The data interface communicates a first data with the first preamble via the first data line and communicates a second data with the second preamble via the second data line. The respective length and/or respective pattern of each preamble are adjustable and/or programmable.
