This section discusses the features of the LVAUX I/O standards. For parameters not listed in this section, refer to the standard specifications listed in UltraScale Architecture SelectIO Resources User Guide (UG571). The LVAUX I/O standards are listed in the following table. These standards are available for HP I/O banks only. No DCI versions of the LVAUX I/O standards are available.

  • Single-ended LVAUX I/O standards
    • LVCMOS12_LVAUX
    • SSTL12_LVAUX
    • MIPI_DPHY_LVAUX_LP
    • AIO12_LVAUX
  • Differential LVAUX I/O standards
    • LVDS12_LVAUX
    • DIFF_AIO12_LVAUX
    • DIFF_SSTL12_LVAUX
    • MIPI_DPHY_LVAUX_HS
  • LVAUX I/O standards that support uncalibrated termination for HP I/O banks
    • SSTL12_LVAUX
    • DIFF_SSTL12_LVAUX
    • AIO12_LVAUX
    • DIFF_AIO12_LVAUX
Note: System monitor external analog inputs (I/O standard = ANALOG or ANALOG_SE) are not supported in LVAUX mode HP I/O banks. Instead, if HD I/O are available in the device, consider routing external analog inputs through an HD I/O.

The LVAUX I/O standards are very similar to industry I/O standards (for example, SSTL12_LVAUX is derived from the SSTL12 I/O standard). The differences are primarily to optimize the design using LVAUX mode.
