Abstract
A redundant synchronous clock distribution system is provided comprising at least a first and a second clock module and first and second clock distribution branches adapted for synchronizing at least one clock slave module connected downstream to the redundant synchronous clock distribution system. Each of the first and second clock modules are adapted to act as a master clock module or a slave clock module. A clock switchover module is adapted to switch each of the first and second clock modules to change between the master mode and the slave mode. The clock switchover module comprises a flip-flop-circuit having a first circuit part and a second circuit part, wherein the first circuit part is located on the first clock module and the second circuit part is located on the second clock module.
