1. Guaranteed by design and characterization. Not 100% tested in production

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. 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).

5. The total variation of all VCROSS measurements in any particular system. Note that this is a subset of VCROSS min/max (VCROSS absolute)

allowed. The intent is to limit VCROSS induced modulation by setting VCROSS to be smaller than VCROSS absolute.

6. Measured from single-ended waveform.

7. Measured with scope averaging off, using statistics function. Variation is difference between min. and max.
