The second type of interface implemented is the terminated, single-ended interface standard. This group of inter-
faces includes different versions of SSTL and HSTL interfaces along with CTT, and GTL+. Usage of these particu-
lar I/O interfaces requires an additional VREF signal. At the system level a termination voltage, VTT, is also required.
Typically an output will be terminated to VTT at the receiving end of the transmission line it is driving.
The third type of interface standards are the differential standards LVDS, BLVDS, and LVPECL. The differential
standards require two I/O pins to create the differential pair. The logic level is determined by the difference in the
two signals. Table 6 lists how these interface standards are implemented in the ispXPGA devices.
