I am using this software to use the evaluation board EVAL-ADF4360.
The register value was calculated in advance under the following conditions.
RF Output Freq = 272.275 MHz
PFD Freq = 25 kHz
N counter = 10891
N = P * B + A ---> B: 1361 A: 3 (P = 8)
N Counter LATCH: C5510E
However, if the same conditions are entered in this software, the register values
will be different. N Counter LATCH: C5510A
Also, even if you operate the up and down arrow keys of Main Futures
to raise or lower the set frequency, the register value does not change.
N Counter LATCH: C5510A When RF Output Freq = 272.25 MHz
N Counter LATCH: C5510A When RF Output Freq = 272.275 MHz
The same register value will be obtained at the next frequency.
N Counter LATCH: C5511E When RF Output Freq = 272.375 MHz
N Counter LATCH: C5511E When RF Output Freq = 272.400 MHz
Is it my calculation mistake?
However, I think it is strange that the values of the N counters are the same even
though the output frequencies of the PLLs are different.
