Unfortunately, an external clock input is required to be applied to J1 on the AD9136 Evaluation Board (AD9136-FMC-EBZ) for it to function. It doesn't have an onboard clock oscillator.
Please refer this link: https://wiki.analog.com/resources/eval/dpg/ad9136-fmc-ebz for the documentation on how to use the AD9136-FMC-EBZ.
