Part Number: LMX2594
HI, staff
Formula of fINTERPOLATOR
LMX2594 datasheet (SNAS696C) page35 Table18 shows the calculation formula of fINTERPOLATOR as follows.fINTERPOLATOR = fVCO / (IncludedDivide × SYSREF_DIV_PRE)
Similarly, the following formula is described in step3 of page39 SYSREF Procedure.fINTERPOLATOR = fVCO / IncludedDivide / SYSREF_DIV_PRE
Which is the correct formula?I think page35 is more correct?
best regardscafain
Hi Cafain,
Both are correct and they are equal but expressed in a different way only.
for example:
100 / (2x5) = 100 / 10 = 10.
100 / 2 / 5 = 50 / 5 = 10.
