The differential HSTL I/O standard is used for the applications designed to operate in
0 V to 1.2 V, 0 V to 1.5 V, or 0 V to 1.8 V HSTL logic switching range. The Cyclone III
device family supports differential HSTL-18, HSTL-15, and HSTL-12 I/O standards.
The differential HSTL input standard is available on GCLK pins only, treating the
differential inputs as two single-ended HSTL and only decoding one of them. The
differential HSTL output standard is only supported at the PLL#_CLKOUT pins using
two single-ended HSTL output buffers (PLL#_CLKOUTp and PLL#_CLKOUTn), with
the second output programmed to have opposite polarity. The standard requires two
differential inputs with an external reference voltage (VREF), as well as an external
termination voltage (VTT) of 0.5 × V
