5.2.7.2 Revertive Selector Card [1204-2E]
The Revertive Selector Option Card provides automatic failover capability, using one option
card slot for a single output signal.
Operating Principle
The output follows the selected input. Signals can be 1PPS, 10MHz, 5MHz or 1MHz.
Input “A” is selected if present and valid. If input “A” disappears, or if power to host
SecureSync is interrupted, input “B” is presented at output “OUT”.
As soon as input “A” becomes valid again, the output switches back to use “A” as source.
At power-up or module reset, there is a timed delay before input “A” is presented. This allows
reference at input “A” to stabilize before being used.
