Abstract:
1. An electronic system, comprising: a first backplane for distributing timing signals, power, and control signals to electronic circuitry coupled to said first backplane, wherein said first backplane comprises a first clock module for generating said timing signals; a second backplane for distributing timing signals, power, and control signals to electronic circuitry coupled to said second backplane, wherein said second backplane comprises a second clock module for generating said timing signals; and an electrical connector coupling said first clock module to said second clock module for communication of a timing signal, wherein said first clock module comprises a circuit for detecting the presence of said electrical connector, said first clock module providing said timing signal to an output port coupled to said electrical connector in response to said circuit detecting the presence of said electrical connector, and said second clock module synchronizes to said timing signal communicated via said electrical connector; and wherein said first and second clock sense modules comprise clock sense logic for detecting a substantially constant amplitude signal fault associated with one of said plurality of hot-swappable oscillator (HSO) devices.
