Part Number: DRA756
Hi expert:
We meet EMC issue and we want to change OSC0 20MHz input and OSC1 19.2MHz input use spectrum spread function's clock.
1. OSC0 20MHz spectrum spread is 20MHz +/- 0.25%
2. OSC1 19.2MHz spread spread is 19.2MHz +/- 0.125%
compare data sheet J6 20Mhz jitter < 0.01 tc. So 20MHz the jitter need < 0.5ns
Now the spectrum spread clock tc change from +/- 0.3ns. It meet spec request.
But we did not know whether those clock roaming will affect J6 DPLL performance.
Could you please check whether J6 can use those kind of spectrum spread clock?
Best Regards!
