Hi All,

Does anyone have Phase Noise measurements on DAC38RF80EVM?

Priority to input 5200GHz , Output 850Mhz.

Thanks

Hi Jim,
Customer would like to understand what is the phase noise floor of the DAC.
From the measurements you've attached it seems like if a better source than SMA100A will be used - a better phase noise can be achieved.
Any chance anyone on the team can repeat these measurements with SMA100B ?
f_dac=5120MHz ; f_data=320Msps ; int x16 ; fout=150-1000MHz ?

Regards,
Nir

Nir,

We will try to do this on Monday if the analyzer is available.

Nir,

Data attached using a SMA100B and a Agilent E5052A signal source analyzer.
