Note1: VDDQ = 1.7 V; VOUT = 1.42 V. (VOUT-VDDQ) / IOH must be less than 21 ohm for values of VOUT
between VDDQ and VDDQ - 280 mV.
Note2: VDDQ = 1.7 V; VOUT = 280 mV. VOUT / IOL must be less than 21 ohm for values of VOUT between
0V and 280 mV.
Note3: The dc value of VREF applied to the receiving device is set to VTT.
Note4: The values of IOH(dc) and IOL(dc) are based on the conditions given in note 1 and 2. They are used
to test drive current capability to ensure VIHmin plus a noise margin and VILmax minus a noise
margin are delivered to an SSTL_18 receiver. The actual current values are derived by shifting the
desired driver operating points along 21ohm load line to define a convenient current for
measurement.
Note5: The VDDQ of the device under test is referenced.
