    摘要: A fail-operational/fail-operational fault tolerant clock includes a voting core comprised of triple redundant clock modules (30, 40, 50) and a floating hot spare module (60). Each module includes a voter (84) and fault detection, identification and reconfiguration circuitry (82) which operates to substitute the floating hot spare module produced clock signal for a failed voting core module signal without the introduction of transients or an asynchronous voted output. The modules (30, 40, 50, 60) are all preferably formed on a single semiconductor chip which includes isolation guard rings (32, 42, 52, 62) and independent power leads (34, 44, 54, 64) in addition to isolation buffering and point-to-point wiring to enhance fault tolerance.

    摘要: A tightly synchronized fault tolerant clock has n+1 substantially identical modules for synchronizing the clock signals of the modules and masking out faults in up to n modules. Each module has an oscillator comprising an amplifier and a regenerative feedback path. The feedback path includes a resonator for determining the oscillation frequency, a variable trimming capacitor for establishing synchronization among the oscillators in the individual modules, an isolation buffer network to eliminate single point failure and to establish a fault containment region, and a majority voter network for maintaining tight synchronization among the oscillators and masking out faults in the individual modules.

    摘要: A synchronizing circuit comprises a plurality of substantially identical modules for receiving respective asynchronous input signals and respective local clock signals with the local clock signals of the respective modules being substantially synchronized. Each module of the synchronizing circuit comprises a de-metastabilizer stage, a global synchronizing stage and a majority edge detector and voter network. The de-metastabilizer stage receives the input signal of the module and provides an output signal free of glitches and metastable conditions, synchronized to the local clock signal. The global synchronizing stage receives the output signals of the de-metastabilizer stage of each module and provides respective output signals synchronized to the local clock signal. The majority edge detector and voter network receives the output signals of the global synchronizing stage and outputs a voted output signal synchronized to the other modules' voted output signals and to the local clock signal.
