[time-nuts] [OT] MB506 pre-scaler module ??

[Dave]

Has anyone got experience of using these ??

MB506 Module <https://www.ebay.co.uk/itm/255079972208>

I need some sort of module to be able to cover up to 1Ghz with my GPSDO 
referenced 100Mhz counter.

The minimum division factor is 64 which is a bit higher than I want 16 
(or 10) would be better. Perhaps someone
can suggest an alternative prebuilt module ??

Regards,
Dave
