ABSTRACT:
A synchronized clock system, for use with an electronic system having several system nodes requiring a synchronized clock signal. The clock system may be formed in either discrete form or in integrated form, or in any combination, and includes a first synch bus and a second synch bus, isolated from the first synch bus, and at least one pair and preferably several pairs of SXO modules connected to the busses in alternating fashion. Each of the system nodes is connected at a different one of any number of arbitrarily selected connection points anywhere along the first bus. The points along the busses at which the SXO modules are connected are spaced roughly equidistantly apart. The system nodes are connected to the bus by means of signal conditioning circuits, which may include correction circuits, an amplifier, a frequency multiplier, a logic translator and a fan buffer.
