I had 3 questions from my customer as below. Could you support them?
Q1) My customer has been using "CoreLoader" to confirm the register settings of LMK04803.
But the customer cannot set "1" to both "Doubler" and "R Counter" at the same time..
Could you tell me the reason why we cannot set "1"?
For example, although we try to be 10MHz clock as ref-signal by using input 10MHz, we can only set both "2", not "1".
I have guessed the reason is from the LMK04800 datasheet description "7.6.2.1 PLL2 FREQUENCY DOUBLER", due to we can minimize the noise by setting "2"... Is my idea correct?
Q2) About the noise, which frequency is better to use for the input signal to minimize the noise, "higher frequency input" or "lower one"?
Q3) The influence of "thermal"
It seems to be easily getting the influence of thermal when the customer is measuring the device.
Could you please advise me how to do to reduce the influence, e.g. should use "cooling fan" or should use something "heat sink"?
Thank you for your support in advance.
Best Regards,
