Hi

I just want to ask about SPI interface in ADF4350. On datasheet there is an information that interface is 1.8 V compatible, but levels on ADF4350 evaluation board are 3.3 V. I didn't find any detailed information in datatsheet about that. So could I connect ADF to i.e. FPGA pins working with 3.3 V LVTTL safely?

 

Best regards
