AD9910 EvalBoard PDCLK External control

Hello...

 

In my application, I need to have complete external control of the AD9910 as well as using the PP for modulation. I have done as you recommend in the EvalBoard datasheet, and remove/disable the jumpers. However, there is something here that I either do not understand and do not make sense for me. It is that the PDCLK passes by the buffer U12, being this one of the IC you disable when you want to use the EvalBoard with external control.

As doing this, of course there is not any signal out on the J8 connector.

 

Is the only alternative to patch the board? is it possible to get gerbers?

 

Thanks
