High speed clock source 
Clk20 is a clock source module that plugs into the XBERT and ParalleX? Chassis. The clock works over a continous range from 78.125 MHz to 20 GHz MHz. Functionally it is not bound to the EBERT modules hence it can be used for driving any other devices, too. It has an optional divided clock output to offer a subrate trigger for oscilloscopes that have limited trigger bandwidth.
It works very well as clock multiplier either.
