Current Strength

The output buffer for each Stratix V device I/O pin has 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 I/O standards have
several levels of current strength that you can control.
programmable current strength settings for Stratix V devices.
Table 5–9. Programmable Current Strength Settings
Altera recommends performing IBIS or SPICE simulations to determine the best
current strength setting for your specific application.
