The voltage levels 0 and 1.8v are mentioned for enabling and disabling data trigger for AD9694 Eval board in the post, respectively. On the other hand, in Xilinx Spartran-7 FPGA data sheet , the high voltage range is mentioned between 1.2v and 3.3v while within “Quick Start Guid” for ADS7-V2EBZ FPGA of the AD9695 Eval Board, the low voltage range is provided between 0 and 1.5 v.
I appreciate if you can clarify the confusion and provide the specs of the input TRIG port for ADS7-V2EBZ (i.e. Maximum voltage or current).
