My requirement is as below:

Input=25MHz,

CLK0，CLK1：156.25M LVPECL;

CLK2，CLK3：125M LVDS;

CLK5，CLK6：50M LVPECL。

Would you please help to check below register setting if it is right?

R0 (INIT) 0x80020140
R0 0x00000200
R1 0x00000281
R2 0x00000642

    Hi Wanda,

    Moving forward, suggest use TICS Pro to generate the configuration.

    Here is the tics pro configuration file (.tcs), you can open tics pro, select lmk03806 and then load this file.

    Attached also the register setting (.txt). I put fpd = 50MHz, that should return better phase noise.
