Lattice Semiconductor
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 V
Typically an output will be terminated to V
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.
