I can't seem to find anything online about the input frequencies accepted by the Clocker board.
We would like to use it as a distribution amp for an external clock signal, as well as feeding the signal to the hardware in the crate. Is this supported?
In general this sort of thing has to be derived from the schematics (https://github.com/sinara-hw/Clocker/releases/tag/v1.1rc2) because nobody has time to write documentation currently.
Transformers TCM2-43X+ 10MHz-4GHz
...and there are no other components there that clearly have bandwidth limitations, so Clocker should do 10MHz-4GHz.
Yes Clocker is actually intended for use as a distribution amplifier like you describe.
Yep, we (Oxford) use Clocker to ship 10 MHz and 125 MHz around the basement. Two things you might want to consider:
