Hi

 

what are the recommended power levels of the external  reference clock signal (1GHz in my case) applied to the sma connector on the 9910 eval board? I have 10dbm available, but it seems to run fine with 0dbm as well.

ALso, what is the output level at, say, 50Mhz with the default load resistors/xfrm/reconstruction filter when the dac current is set to 20mA ?

 

cheers,

risto
