VREF
VREF(AC)
Reference voltage for SSTL, HSTL, and HSUL I/O Standards.
AC input reference voltage for SSTL, HSTL, and HSUL I/O Standards. VREF(AC) = VREF(DC) + noise. The peak-to-
peak AC noise on VREF should not exceed 2% of VREF(DC)
.
VREF(DC)
DC input reference voltage for SSTL, HSTL, and HSUL I/O Standards.
VSWING (AC)
VSWING (DC)
VTT
AC differential input voltage: AC Input differential voltage required for switching.
DC differential input voltage: DC Input differential voltage required for switching.
Termination voltage for SSTL, HSTL, and HSUL I/O Standards.
VX (AC)
AC differential Input cross point voltage: The voltage at which the differential input signals must cross.
