ADF4350 double check of the Rset value for the EVAL board

Hi,

on my board ADF4350EB2Z rev B, the value of Rset is 4.7K and  the shematic at pag. 6 of the board description pdf  found on the CD shows that, as well.

 

It seems strange to me, the Icp is equal to 5.24mA with 4.7K, but at pag3 of the 4350 datasheet it shows the max Icp = 5mA.

(which is also confermed by the equation Icp = 25.5/Rset that can be found at pag.8 of the same datasheet).

 

Could you tell your opinion please?

 

Thanks

Giovanni
