Hi Dmytro,
I apologize, but I'm having trouble reading the schematic because of its low resolution.

Do you mean change the divide ratio? It appears that you're connecting S7 and S8 for the ADG parts. What you're doing is possible, although the AD9513 isn't intended to change the divider on the fly. That said, you should be able to change the divider by momentarily grounding the SYNCB pin, although I'm not 100% positive. However, it shouldn't be hard to verify this if your board is built.

Try grounding the SYNCb pin and let me know.
