Hello,
For 5CEBA7F27C8N FPGA part, required clarification on VREF[#]N0 pins connection.
For example, Bank 6A is operating at 2.5V and we have considered two I/O standards "2.5V LVDS" and "LVPECL" in Bank 6A.
Based on these two I/O standards considered in Bank 6A, do we need connect "VREFB6AN0" pin to VCCIO of 6A bank or can we connect it to ground? Please confirm

Hi,
VREF is only used for voltage referenced I/O-standards, SSTL and HSTL. Neither LVDS nor LVPECL need it. So GND connection of VREF is the standard option.
