    摘要: In an electronic system having first and second logic devices, a free running on-chip clock signal is generated by the first logic device, where the signal has a frequency that is controlled to match that of a global free-running clock signal received by both devices. The on-chip clock signal is synchronized to a strobe signal received by the first device and that was transmitted in association with a data signal by the second device. A logic function is repeatedly performed as synchronized by the first clock signal, to repeatedly generate one or more bits from the data signal.

    摘要: A frequency control unit has an input to receive a digital downstream strobe signal and an output to provide a controlled delay to the input strobe signal. A downstream latch has a data input to receive a digital downstream data signal and a clock input coupled to the output of the frequency control unit. The controlled delay is essentially equal to a set up time of the latch. A delay element coupled to the output of the frequency control unit further delays the downstream strobe signal by essentially a propagation time of the latch. Output drivers are coupled to the outputs of the latch and the delay element.

    摘要: A simultaneous bidirectional port coupled to a bus combines a synchronization circuit and a data transceiver circuit. The combination data and synchronization transceiver circuit synchronizes the port with another simultaneous data port coupled to the same bus. The combination data and synchronization transceiver circuit includes a driver with a variable output impedance. Prior to synchronization, the driver has an imbalanced output impedance, and after synchronization, the driver has a substantially balanced output impedance.
