Multiple frequency output clock generator system

Abstract From the Canadian patent

A clock generator system for producing a number of multiple frequency digital clock signals for distribution to a number of synchronous, clocked devices include two separate, substantially identically structured clock generator units that operate in lock-step unison. The digital clock signal outputs of one of the generator units is distributed to the synchronous, clocked devices and to a error detection circuit that also receives the digital clock signals from other clock generator unite for comparison with one another. In the event an error is detected, the error detection circuit will produce an error signal to halt operation of the system with which the clock generator system is used, …
