    V
    VCM(DC)
    DC common mode input voltage.
    VDIF(AC)
    AC differential input voltage: The minimum AC input differential voltage required for switching.
    VDIF(DC)
    DC differential input voltage: The minimum DC input differential voltage required for switching.
    VICM
    Input common mode voltage: The common mode of the differential signal at the receiver.
    VID
    Input differential voltage swing: The difference in voltage between the positive and
    complementary conductors of a differential transmission at the receiver.
    VIH
    Voltage input high: The minimum positive voltage applied to the input that is accepted by the
    device as a logic high.
    VIH(AC)
    High-level AC input voltage.
    VIH(DC)
    High-level DC input voltage.
    VIL
    Voltage input low: The maximum positive voltage applied to the input that is accepted by the
    device as a logic low.
    VIL (AC)
    Low-level AC input voltage.
    VIL (DC)
    Low-level DC input voltage.
    VIN
    DC input voltage.
    VOCM
    Output common mode voltage: The common mode of the differential signal at the transmitter.
    VOD
    Output differential voltage swing: The difference in voltage between the positive and
    complementary conductors of a differential transmission at the transmitter. VOD = VOH – VOL.
    VOH
    Voltage output high: The maximum positive voltage from an output that the device considers is
    accepted as the minimum positive high level.
    VOL
    Voltage output low: The maximum positive voltage from an output that the device considers is
    accepted as the maximum positive low level.
    VOS
    Output offset voltage: VOS = (VOH + VOL) / 2.
    VOX (AC)
    AC differential output cross point voltage: the voltage at which the differential output signals
    must cross.
    VREF
    Reference voltage for the SSTL and HSTL I/O standards.
    VREF (AC)
    AC input reference voltage for the SSTL and HSTL I/O standards. VREF(AC) = VREF(DC) + noise. The
    peak-to-peak AC noise on VREF must not exceed 2% of VREF(DC).
    VREF (DC)
    DC input reference voltage for the SSTL and HSTL I/O standards.
    VSWING (AC)
    AC differential input voltage: AC input differential voltage required for switching. For the SSTL
    differential I/O standard, refer to Input Waveforms.
    VSWING (DC)
    DC differential input voltage: DC input differential voltage required for switching. For the SSTL
    differential I/O standard, refer to Input Waveforms.
    VTT
    Termination voltage for the SSTL and HSTL I/O standards.
    VX (AC)
    AC differential input cross point voltage: The voltage at which the differential input signals must
    cross.
