DIFFIO_TX_P/N versus DIFFIO_RX_P/N Cyclone V and others

Hi, Can I use a DIFFIO_TX_P/N of a Cyclone V or other FPGAs as a LVDS input and vica versa? Although there is written TX (transmit) and RX (receive) there is also written DIFFIO (=input/output)....

Correct. You can use 'DIFFIO_rx' pairs as sub-LVDS or LVDS input pairs and 'DIFFIO_tx' pairs as output pairs (or single ended outputs).

You just can't use 'DIFFIO_tx' pairs as inputs.

Cheers,

Alex
