Notes:
1. Using same REFCLK input with TXENPMAPHASEALIGN enabled for up to four consecutive GTX_DUAL sites.
2. Using PLL_DIVSEL_FB = 2, INTDATAWIDTH = 1. These values are NOT intended for protocol specific compliance determinations.
3. PLL frequency at 1.6 GHz and OUTDIV = 1.
4. GREFCLK can be used for serial data rates up to 1.0 Gb/s, but performance is not guaranteed.
