Other Parts Discussed in Thread: CLOCKPRO
Would you please let me know about M value in ClockPro?
If I set fin = 24MHz , and if I choose fout= 24* 1000/1001 =23.97602397MHz,
I can calculate from ClockPro as fout = 24 * 3000 /3003 = 24* 3000/( 7* 429 ) ; Pdiv=7, N=3000, M=429.
Therefore, fout should be 23.97602397MHz ( 0ppm) but Clock Pro putput is 23.976023976024 ( 0.000166ppm error).
Why does it occur ?
I guess M value using in ClockPro is something wrong..
How does Clock Pro calculate M value from N,P,Q,R?
We see N,P,Q,R value ( 18~1Bh, 1C~1Fh), but M value is not defined in the register setting.
How does Clock Pro get M value?
I worried about even I set N,P,Q,R correctly , I might have some error% in fout value.
Thank you for your support
