The differential SSTL I/O standard is a memory-bus standard used for applications
such as high-speed DDR SDRAM interfaces. The Cyclone III device family supports
differential SSTL-2 and SSTL-18 I/O standards. The differential SSTL I/O standard
requires two differential inputs with an external reference voltage (VREF) as well as an
external termination voltage (VTT) of 0.5 × V
connected. The differential SSTL output standard is only supported at PLL#_CLKOUT
pins using two single-ended SSTL output buffers (PLL#_CLKOUTp and
PLL#_CLKOUTn), with the second output programmed to have opposite polarity. The
differential SSTL input standard is supported on the GCLK pins only, treating
differential inputs as two single-ended SSTL and only decoding one of them.
