Hello everyone! I'm using the AD9739A-FMC-EBZ( REV C ) board on KC705,but there myabe some problems with the FMC SPI.  I turn S1 to ADF4350 and P2 select FMC SPI,  I  observe the MOSI wave with Oscilloscope when configure the AD4350, it is only 1.8V not 3.3V,but the SCK wave is 3.3V, both signals from the FPGA are a 2.5V.  And the LD LED does not light, beside these no wave out at the RFout . Does some thing wrong with the FMC SPI MOSI?S
Looking forward to your reply. Thank you!
