Hi,

 

1)I have to generate 22MHz-42MHz frequency by using AD9951 DDS with expected phase noise -135dBc/Hz @ 10KHz.

So I request you to please advice , How much phase noise can be obtained by using AD9951 DDS . ( I am using 100MHz MCLK with -150dBc @ 10KHz)?

2) What type of oscillator MCLK 400MHz (partnumber or datasheet) you used for the AD9951 (please look http://www.analog.com/static/imported-files/data_sheets/AD9951.pdf  page 11, Fig.#16 ,Fig#17 ?

 

 

Thanks
