If external oscillator jitter can be attenuated by LMK03806? Or transfer to output directly?
For example, external oscillator(20MHz) jitter is 1ps(12K to 20M), if the output (312.5MHz) jitter(12K to 20M) can be smaller than 300fs?
It is possible that the LMK03806 could act as a jitter cleaner, it depends upon the distribution of the noise from your source in relation to your loop filter bandwidth. I would recommend looking at the TI Clock Design Tool at: http://www.ti.com/tool/clockdesigntool
This will allow you to simulate the performance of the LMK03806 for your application and determine if it will perform as you expect. This tool will also allow you to import the phase noise profile of your source to get an accurate analysis. Let me know if you have further questions.
Thanks, Jonathan, LMK03806 can attenuate oscillator jitter like a jitter cleaner.
No problem. Just remember that it will not attenuate oscillator jitter in all situations, it will depend on the jitter integration range you are interested in, the oscillator phase noise, and the loop filter and related settings.
