Hi, all fpga: arria 10 quartus II: 18.0 standard I have requirement for the lvds ip, when I have no data output, I need to disable lvds pin dynamically. So I add below design: tx_ser...

LVDS IO-standard has no tri-state feature, independent of FPGA series or Quartus version. You can refer to BLVDS (bus LVDS) if it's fast enough. On Arria 10, there's no BLVDS choice available, you'll use differential SSTL instead.

2 years agoHi FvM,
Thanks for your help.
I found that there's one required choice (Use pseudo-differential buffer) in altera gpio ip. So if I use SSTL IO standard instead of POD io standard, there's no error, right?
