Questions about AD9958 SPI communication

Question

Hello, 
 
 My customer use AD9958 in their board, but they have problems at SPI communication with FPGA. 
 (They don't have AD9958 EVM. And they have experience to use AD9914.) 
 
 Would you confirm their schematic and AD9958 configuration (Register setting & SPI setting) in attached file (AD9958 TEST.pdf)?

 Please confirm their schematic and configurations and advise them. 
 If you need more information about their configuration, please let me know. 
 
 Regards, 
 Se-woong

HI Se-woong , 
 This guide will help you what are the basic things needed to be checked when using the DDS evaluation board via external control. I hope this helps. 
 Although your schematic on the AD9958 seems accurate, I can't verify the FPGA side for now. 
 All the best, 
 Jules)
