i have question regarding AD9172BBPZ board, the signals levels from HMC 7044 are set to 3.3 volts(VCC9_OUT =3.3 V) however the input level to the FPGA chip (kcu 105 board ) can't exceed Vadj (1.8 V) there no risk to connect the two boards???
Moved to the High-Speed DAC section.
That depends on which output driver is being used. VCC9_OUT is the supply pin for CLKout12 which is connected to FPGA. LVDS is a good option to meet the low voltage levels such as you mentioned.
