Why is the DIFFIO_TX85p pin not available on the Stratix EP1S40 device in the 780-pin FineLine BGA package?
BUILT IN - ARTICLE INTRO SECOND COMPONENT
Description The DIFFIO_TX85p pin is not available on the Stratix® EP1S40 device 780-pin FBGA package because the positive pin of this differential pair is not bonded out, and therefore not useable for LVDS. However, the negative pin can still be used as a regular I/O.
