AD9517-4 doesn't work

Hi engineer :

I want to use HSC-ADC-EVALCZ  to configure my AD9517-4 circuit.The scheme as follows.

The Interface is  same as AD9484-500EBZ. Then I loaded AD9517_for_AD9268EVB.cfg and file through SPI Controller.The files as follows.

AD9517-4 cofigure

Then I test the waveform use  oscilloscope of AD9517-4 signal.

REF input (differential)

chip select




But I test nothing on the out5 and out3(always zero level).What's wrong about.Thank you very much.
