Dear ADI engineer:
I want use the adate207 to driver a waveform,but the DR_DATA pin has no output.
I config the register map as below

I put the PAT_PATDATA always at 0X00, PAT_PATDATA,PER_EARLY_T0EN, PAT_DATA_VALID timing diagram is as below.

My understanding based on the datasheet is that the DR_DATA PIN will have an output after 27.5ns,But now there is no output.
Did I misunderstand, please help me .
Thanks very much.
