Table 5–9. DC Characteristics for User I/O Pins Using Differential I/O Standards
I/O Standard
The LVPECL I/O standard is only supported on clock input pins. This I/O standard is not supported on output
pins.
The RSDS and mini-LVDS I/O standards are only supported on output pins.
The differential 1.8-V HSTL and differential 1.5-V HSTL I/O standards are only supported on clock input pins and
PLL output clock pins.
The differential SSTL-18 and SSTL-2 I/O standards are only supported on clock input pins and PLL output clock
pins.
