To a persion concerned.
I had problem for Clock Ouput generation on LMK03318. So, I read relevant register description and found one questionable thing.
Regarding Reference Clock detection, As far as I understand, User should use R29, R25, R18.
My setting for the detection is as below
-. DETECT_BYP = 0 on R29.7
- DETECT_MODE_SEC on R25.7:6 = 00 or 01 , 10, 11
- LVL_SEL_SEC on R25. 3:2 = 00, 01 ,10
With the combination of the above values, I expected Reference clock input should be detected and R18 showed result. But R18 had always 0x00.
0x00 means that Slew Rate Detect status was invalid.
Could you let me know which case Slew Rate Detect is valid at?
thank you
Best Regards
