    摘要: The phase locked loop (PLL) with adjustable phase shift is described. The PLL includes a voltage controlled oscillator which is capable of generating multiple phase shifted output signals, and multiple phase detectors capable of determining the phase differences between the output signals and a reference clock. The PLL further includes a weighting device capable of weighting the phase differences and generating a control signal for the voltage controlled oscillator.

    摘要: The apparatus for transmitting and receiving data according to the invention contains a transmitter (1) for serial data transmission and a receiver (3) for receiving a transmitted data signal (g(t)). The receiver (3) in turn comprises a first sample latch (11) for sampling the received data signal (g(t)) with a first clock (f2) and for generating a first sample value (an). The receiver (3) also comprises a second sample latch (13) for sampling a first shifted received data signal (g(t)+V1) with a second clock (f1) and for generating a second sample value (yn). The receiver (3) further comprises a third sample latch (14) for sampling a second shifted received data signal (g(t)−V1) with the second clock (f1) and for generating a third sample value (zn). Finally the receiver (3) comprises a logic unit (15) for recovering data (dn) out of said first, second and third sample values (an, yn, zn).
