Hi Ahmed,
We suggest use TICS-Pro to configure the device to your desired configuration, then in the Raw Registers tab you can export all the registers to a text file. Please note that we will be updating TICS-Pro very soon but it is also good for you to try it now to get familiar with it.

Thank you very much Julian and Noel, i appreciated your prompt support.
Could you please let me know the 2nd/3rd harmonic level ?
also could you please let me know the consideration of the Power disipation and if i need heatsink and what is ideas of heatsink ?
thanks in advance .

Hi Ahmed,

The device consumes less than 200mA current, I don't think a heat sink is required. You can find the 2nd harmonics data in the electrical table, which is about -25dBc. 3rd harmonics will be a bit higher because of the output divider.

Hi Ahmed,

Sorry I mis-read it as LMX2581.
the correct current consumption is about 350mA, depending on your actual configuration. Anyway, a head sink is not required. Make sure you have sufficient ground via at the ground paddle to dissipate the heat to the pcb.
