1Guaranteed by design and characterization, not 100% tested in production. IREF = VDD/(3xRR). For RR = 475Ω (1%), IREF =
2.32mA. IOH = 6 x IREF and VOH = 0.7V @ ZO=50Ω (100Ω differential impedance).
2 Measured from differential waveform
3 Slew rate is measured through the Vswing voltage range centered around differential 0V. This results in a +/-150mV window around
differential 0V.
4 Matching applies to rising edge rate for Clock and falling edge rate for Clock#. It is measured using a +/-75mV window centered on
the average cross point where Clock rising meets Clock# falling. The median cross point is used to calculate the voltage thresholds
the oscilloscope is to use for the edge rate calculations.
5 Vcross is defined as voltage where Clock = Clock# measured on a component test board and only applies to the differential rising
edge (i.e. Clock rising and Clock# falling).
6 The total variation of all Vcross measurements in any particular system. Note that this is a subset of V_cross_min/max (V_cross
absolute) allowed. The intent is to limit Vcross induced modulation by setting V_cross_delta to be smaller than V_cross absolute.
7 Includes overshoot and undershoot.
8 Measured from single-ended waveform
9 Measured with scope averaging off, using statistics function. Variation is difference between min and max.
