Hi, this is my first time connecting an external component to the FPGA. The ADC's output can be 5 v .. I'm using digilent spartan 3 board, where Vcco is connected to 3.3 V .. should I interface the ADC to it direcrly since the FPGA has internal clamp diodes ? or is it better to use a tranciever?

Thanks :!:

ADC-FPGA interface

You must somehow limit the input current.
The Xilinx answer database talks about 5V interfacing:
