Do Altera devices have fail safe circuitry for differential receivers?

Description

No, Altera® devices do not have fail safe circuitry for differential receivers.  If your application does not actively drive pins configured as differential inputs, Altera recommends adding external components so the device inputs are not left floating.

See the related solution below for a list of Altera devices that do support floating LVDS inputs and the associated precautions if you do not use external fail safe circuitry on these devices.
