Interfaces and DPA in Stratix IV Devices
The output buffer for each Stratix IV device I/O pin has a programmable current
strength control for certain I/O standards. Use programmable current strength to
mitigate the effects of high signal attenuation due to a long transmission line or a
legacy backplane. The LVTTL, LVCMOS, SSTL, and HSTL standards have several
levels of current strength that you can control.
