  1. Hi, I would like to know what IO standard would I use if I want to input a differential signal to two adjacent PMOD headers on PMOD JB. This differential signal will be an input to a buffer on the FPGA. The current xdc file on github uses LVCMOS33 as a default standard as shown below. set_property -dict { PACKAGE_PIN E15 IOSTANDARD LVCMOS33 } [get_ports { Input_data }]; #IO_L11P_T1_SRCC_15 Sch=jb_p[1] set_property -dict { PACKAGE_PIN E16 IOSTANDARD LVCMOS33 } [get_ports { Input_data }]; #IO_L11N_T1_SRCC_15 Sch=jb_n[1] Would it be fine if I use LVCMOS33 or should I use another IO standard and if so which one should I use. I am using the Arty A7 100t board. Thank you
