From my project, I need to fanout high performance clocking outputs @ 6.4GHz. On the ADCLK944 datasheet, it only shows the phase noise performance @ 1 GHz. Its noise floor is about -150dBc/Hz for fin = 1GHz. What is the estimated phase noise and noise floor for fin = 6.4GHz? What is the crosstalk spec for fin = 6.4 GHz?
Any response would be appreciated.
