[hpsdr] GIBRALTAR LO generation question

[Rick Hambly (W2GPS)]

Lyle,

That sounds OK.  Should it be a differential signal?

Hello Rick!

Please consider providing a 10 MHz signal (through a CPLD or FPGA or 
???) to the Atlas backplane.  It can be used as a frequency reference 
for applications that are less sensitive to jitter, such as syncing up 
the clocks on the ADCs, DACs and CODECs on Janus.
