Other Parts Discussed in Thread: LMX2594
Hello,
On the datasheet, it is written that the performance is measured using a clean 100-MHz input reference but no additional information is provided about how clean it is.
I know that the phase noise is contributed not only by input clock reference but also by PLL noise and VCO noise but taking only the OSC input into account, as an example, to achieve the performance given on LMX2694-EP datasheet page 10 ( figure 6.4) which is 61.2 fs jitter when the output frequency is 8.1 GHz, can we say that the jitter of input clock reference (crystal oscillator) must be lower than 61.2 fs?
Regards,
