1
Guaranteed by design and characterization, not 100% tested in production. CL = 2pF with Zo = 85 differential trace 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 Vcross_min/max (Vcross  
absolute) allowed. The intent is to limit Vcross induced modulation by setting -Vcross to be smaller than Vcross absolute.

Notes:  
1 Guaranteed by design and characterization, not 100% tested in production.  
2 All Long Term Accuracy specifications are guaranteed with the assumption that the input clock complies with CK420BQ/CK410B+  
accuracy requirements (+/-100ppm). The 9ZXL1950 itself does not contribute to ppm error.
