About ADF4360-x Software V4.1.4

Hi

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.

Regards.
