Abstract:
A method of synchronizing a plurality of local clocks in a data bus system having a plurality of nodes, each node having one of said plurality of local clocks, said method comprising the steps of:a) initiating formation of a data bus configuration for said data bus system, wherein each node includes a local clock generator, at least one port, and at least one clock recovery circuit coupled to a respective port, wherein a coupled port represents a port coupled to another port; b) for each node, assigning each coupled port one of a plurality of identifiers based on predetermined criteria said identifiers including a first identifier and a second identifier; and c) for each node which has a first identifier port, changing a clock source for a respective local clock of said node from a respective local clock generator of said node to a particular clock recovery circuit of said node, wherein said particular clock recovery circuit recovers a transmitted local clock of a transmitting node coupled to said first identifier port via a second identifier port.
